please pull some printk fixes from - Use lazy irq_work for waking printk kthreads. - Flush pending irq_work before destroying printk kthreads. - Remove redundant WARN() when a printk kthread can't be created. - Typo fix. The primary motivation for making the irq_work lazy is that pending IRQs block suspending and entering idle states on Tegra20 and Tegra30 platforms. They even did not boot after converting uart 8250 console driver to the nbcon API. It should be acceptable because printk kthreads are used for non-emergency messages. They have to wait until they get scheduled anyway. This seems to be the least hacky solution which might even have some positive effect in reducing the IRQ noise. And it allows to keep the converted uart 8250 console driver in 7.3. The discussion about the Tegra problems can be found at https://lore.kernel.org/lkml/[email protected]/ https://lore.kernel.org/all/[email protected]/
If this is too late in the cycle, no worries, I'll wait and do it in the second week of the v7.4 merge window for its -rc1. I only discovered earlier this week that Coccinelle had missed a bunch in the v7.0 tree-wide conversions due to its (silent) failure to parse functions using scope_guard() and family[1]. Since -rc2 hadn't cut yet, I thought if you wanted these now, I could get them to you. Anyway, here's the commit log repeated: This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

f2fs-for-7.3-rc1
In this round, key enhancements focus on reducing inode management memory
overhead, introducing resizable tail sections with unified pinned allocation,
and boosting I/O throughput via parallel multi-device flushes and asynchronous
f2fs_write_end_io() execution. We also add dynamic device alias reservations to
allow on-the-fly space donation from user partitions.
Alongside these features, critical bug fixes resolve folio race conditions,
lingering dirty flags, dentry and block counter leaks, and potential deadloops
in f2fs_fsync_node_pages(). Additional stability patches address error-path
handling across symlink, sync, and rename/unlink operations, prevent pinned file
fragmentation, and correct segment migration and free section accounting in
free_segment_range.
Enhancement:
- reduce memory footprint of ino management
- support dynamic reserve/release for device aliasing
- issue multi-device flushes in parallel
- add a way to run f2fs_write_end_io() asynchronously
- support resizable tail section and unify pinned allocation
Bug fix:
- fix to pass folio->index to f2fs_sanity_check_node_footer()
- fix folio_nr_pages() race after put in large folio invalidate
- fix to clear dirty flag on folio in error path
- accurately adjust free_sections during free_segment_range
- fix to avoid potential deadloop in f2fs_fsync_node_pages()
- fix the error path in symlink, device alias in rename/unlink,
f2fs_sync_fs,
- fix to migrate all curseg types during free_segment_range
- fix to avoid pinfile fragment on fragment:{block, segment} mode
- fix valid block count leak on data block allocation failure
- fix dentry folio leak in find_in_level
- reject overlapping move range after len expansion
- fix some bugs related to file pinning, GC functions, i_size.
And, the series includes a number of minor bug fixes.

upcoming -rc cycle. I'm seeing no present or upcoming conflicts. Thanks. mm.git review status for linus..mm-stable Everything: Total patches: 171 Reviews/patch: 1.83 Reviewed rate: 82% Excluding selftests: Total patches: 149 Reviews/patch: 1.77 Reviewed rate: 80% Excluding selftests and maple_tree: Total patches: 129 Reviews/patch: 1.99 Reviewed rate: 89% Summary of patch series in this merge: - "mm/rmap: index MAP_PRIVATE file-backed folios by anonymous pgoff" (Lorenzo Stoakes): Index MAP_PRIVATE file-backed folios by their anonymous page offset to resolve confusion around reverse mapping for zeroed and CoW'd file-backed memory. Use this new VMA anonymous page offset tracking to eliminate index conflicts and lay the foundation for scalable CoW performance improvements. - "promote mapped executable folios after first usage for MGLRU" (Baolin Wang): Make MGLRU's protection of mapped executable file folios more reliable. Follow the classical LRU's logic, promoting mapped executable file folios after their first usage to give executable code a better chance to stay in memory and improve workload performance. - "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong Chen): Fix per-node proactive reclaim interface's ignoring the swappiness parameter when CONFIG_MEMCG is disabled by consolidating sc_swappiness() into a single function that checks proactive_swappiness regardless of kernel configuration. - "mm/vmscan: reduce lru_lock contention via vmstat-derived scan-balance cost" (Usama Arif): Reduce lru_lock contention in the reclaim path by deriving scan-balance costs from vmstat counters rather than lock-acquired producer updates. Read and decay these cost signals on the reclaim side under a dedicated per-lruvec lock, reducing total LRU lock wait time by over 60% without impacting scan throughput. - "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky): Fix two low-risk zram bugs which Sashiko spotted in drive-by review. - "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's memcg" (Zi Yan): Fix xas_split_alloc() by enabling target folio memcg charging during splits and adding the missing __GFP_ACCOUNT flag for proper XArray node memory accounting. - "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick): Replace hardcoded binary names in selftests/mm/.gitignore with a generic pattern-matching rule to automatically ignore generated test files and avoid manual updates when adding new tests. - "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon): Make the incompatibility between FLATMEM and NUMA explicit in mm/Kconfig and remove the unused pgdat_page_ext_init() function. - "zram: fix zstd error paths and add parameter validation" (Haoqin Huang): Clean up zram compression backends by removing redundant error cleanup, adding parameter and dictionary validation, auto-prefixing algorithm error logs, and resetting parameters prior to reinitialization. - "zram: fix stale scan bounds after reinitialization" (Longlong Xia): Prevent out-of-bounds slot accesses during concurrent zram resets by moving table scan bound calculations under dev_lock in writeback_store() and read_block_state(). - "add anon mTHP collapse test cases" (Baolin Wang): Extend selftests helper functions to support arbitrary page orders and add new test cases and options for mTHP collapse in khugepaged. - "selftests/mm: Handle unsupported and transient test conditions" (Muhammad Usama Anjum): Update MM selftests to report a SKIP status instead of a failure when required kernel or filesystem features are unsupported, while adding retry logic for transient page migration errors. - "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia): Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled and extend shrink_memcg() to support batch writeback for improved writeback efficiency. - "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren Baghdasaryan): Introduce an IOCTL-based binary interface for memory allocation profiling that enables kernel-side filtering before per-CPU counter aggregation. This eliminates the text-parsing overhead of /proc/allocinfo and provides up to a 20x speedup by transferring only filtered allocation data to userspace. - "better block swap batching and a different take on swap_ops v5" (Christoph Hellwig): Refactor block swap I/O to use swap_iocb for batching instead of single-bio requests and rebase the swap_ops interface, achieving faster swap throughput during kernel builds. - "mm: kmemleak: reduce transient false positives by confirming leaks" (Catalin Marinas): Reduce false-positive kmemleak reports by combining two kmemleak enhancements that add a second confirmation scan and a configurable minimum unreferenced scan count module parameter. - "mm: kmemleak: default min_unref_scans to 2 for verbose kernels" (Breno Leitao): Auto-scanning kernels can generate false-positive memory leak reports on single scans, so this patch defaults min_unref_scans to 2 when CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second confirming scan. - "swap_ops updates" (Christoph Hellwig): Batching I/O for synchronous swap devices causes performance regressions and filesystem-based swap suffers from double-indirection overhead. This series resolves both issues by reintroducing per-folio writes for synchronous swap and allowing filesystems to directly export their own swap_ops. - "mm/khugepaged: several cleanups" (Nico Pache): khugepaged accumulated redundant state-checking patterns and outdated comments following mTHP integration. Introduce dedicated helpers for PTE validation and event counting while refreshing the internal documentation. - "maple_tree: lock checking and clean ups" (Liam Howlett): Syzbot reports incorrectly blame memory management exit paths for locking bugs, maple tree erase operations risk allocation failures without gfp flags and internal documentation lacks clarity. Improve lock error detection, update docs, fix race and allocation edge cases and optimize erase allocations using a fallback to GFP_KERNEL | GFP_NOFAIL.

A handful of late-arriving fixes, a Japanese translation that was ready long ago but fell through the cracks, and an update to the Italian translations.
I know this is running late, I have an alternate PR with just the bug
fixes if you prefer. I ended up having to drop a couple of patch sets,
and pulled in a couple of the simpler bug fixes late. I have a few
more bug fixes coming but they will have to wait a week or two.
These patches have all been merge, build, and regression tested
against your tree as of yesterday. The majority of the code has had
several weeks of testing, both in linux-next and the Ubuntu kernels.
The biggest functional change is Jann Horn's fix for how aparmor is
doing stale cred updates after a policy replacement.
apparmor: fix cred UAF caused by begin_current_label_crit_section()
It moves the update to be done during task_work at the end of the
syscall.
The current patch set has one major feature which is allowing policy
to be compressed in userspace instead of after the fact (in kernel) if
we need to hold onto it for CRIU/introspection. This is responsible
for the majority of the diffstat in apparmorfs.c
The other major change is to do with network mediation. It is a lot of
code churn but does not do any functional changes to mediation. It
moves the code around, and refactors it to use newer patterns for
consistency, and in preparation for some improvements in mediation in
a future patchset. This change is responsible for the majority of the
diffstat in lsm.c and af_inet.c
The cleanup of the mount mediation to the newer patterns and macros is
responsible for the majority of the mount.c diffstat.
With the constification of code being the next largest contributor to
the diffstat.

of the power sequencing updates and it does a tree-wide rename of two of the public functions to better reflect their actual semantics. This has been acked by the maintainers of the affected subsystems. Thanks, Bartosz power sequencing updates for v7.3-rc1 - rename pwrseq_power_on/off() to pwrseq_enable/disable() tree-wide
hwspinlock updates for v7.3 Propagate single-lock registration failures from radix_tree_insert(), making caller sanity checks effective. Update the hwspinlock MAINTAINERS repository URL to the current remoteproc tree.
rpmsg updates for v7.3 Fix a GLINK endpoint teardown deadlock during driver detach and order SMEM FIFO reads after the remote-updated availability check. Prevent duplicate rpmsg character endpoint teardown when remoteproc shutdown races with RPMSG_DESTROY_EPT_IOCTL. Replace unsafe string and sysfs formatting helpers, and correct the unregister_rpmsg_driver() return value documentation.
remoteproc updates for v7.3 Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores executing from dual-port BRAM, with clock and reset control and support for firmware without a resource table. Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends, and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings, and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur. Enable BAM-DMUX child devices for PAS modems and fix PAS memory protection, handover, shutdown, and resource lifetime handling. Harden remoteproc lifecycle handling by attaching asynchronously, stopping crashed processors, synchronizing crash work with removal, and forcing shutdown before device resources are released. Reallocate resources during attach recovery and fix several reference and error-path leaks. Add Xilinx R5 crash detection and move RPU start and stop sequencing into the platform firmware driver. Consolidate write-combining carveout mapping callbacks, use correct I/O-memory accessors, and share optional ELF resource-table handling across drivers. Convert the TI Wakeup M3 binding to DT schema, correct Qualcomm and generic remoteproc bindings, and harden resource-table iteration against signed-offset out-of-bounds accesses.
Could you consider these extra patches for 7.3-rc1?
All commits are quite small, so I guess there's no need to delay them.
One patch from Geert addresses EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS
again, so that "make savedefconfig" won't write the needless default
value to the defconfig file. It avoids unnecessarily enlarging the
defconfig files and reduces churn when updating them.
In addition, there are small changes to enhance the page cache sharing
feature to support SEEK_{HOLE,DATA}, splice(), and large folios.
The remaining one fixes an issue in z_erofs_gbuf_growsize() as below.
All commits have been in -next and no potential merge conflict is
observed.
Thanks,
Gao Xiang
Changes since last update:
- Fix up the EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS default logic so that
"make savedefconfig" won't write the needless default value to the
defconfig file
- Add support for SEEK_{HOLE,DATA}, splice() as well as enable large
folios in inode_share mode
- Fix z_erofs_gbuf_growsize() after the previous buffer resizing fails
TTY / Serial driver updates for 7.3-rc1 Here is the "big" set of tty and serial driver updates for 7.3-rc1.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

This is ntfs update pull request for v7.3-rc1. I add a description of Thanks! This contains 52 commits with improvements to compression support, metadata handling, error propagation, and filesystem robustness. New feature: - Add optional read support for Windows System Compression (WOF). Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading WOF-compressed files through the NTFS page-read path. This includes parsing REPARSE_TAG_WOF, handling resident and non-resident WOF metadata and compressed chunks, and adding kernel-side XPRESS 4K/8K/16K and LZX 32K decompressors. The codecs use a common transparent compression interface shared with LZNT1. WOF support is read-only and disabled unless explicitly enabled. Other changes: - Harden malformed filesystem handling and error paths. Add bounds and consistency checks for mapping pairs, run lengths, MFT locations, update-sequence offsets, non-resident attributes, compressed attributes, index roots, and bitmap scans. Prevent out-of-bounds accesses in decompression, MFT allocation, and index conversion paths, clean up MFT mappings and attribute search contexts on failure, and propagate attribute and inode initialization errors correctly. - Improve compressed-file I/O path. Fix compressed writes on large-page and highmem systems, reuse compression contexts and output workspaces, avoid unnecessary reads for full-unit overwrites, and submit one bio per compressed write unit. Write replacement data before publishing the new mapping, correctly handle zero-filled compressed blocks, and fix initialized-size and folio state updates after compressed writes. - Synchronize resident reads with MFT record updates. - Validate the final EA stream size before modifying existing data, rewrite the stream safely when replacing entries, restore the previous state when metadata updates fail, and remove the EA attribute pair when the last entry is deleted. - Apply Windows filename restrictions only when windows_names is enabled. - Allow index roots to relocate to extent MFT records when the base record lacks sufficient space. - Move non-resident attribute payload data before shrinking its record. - Correct resident-to-non-resident conversion when compression or sparse flags are enabled. - Prepare file allocation and initialized-size updates before buffered or direct I/O submission, and use pagecache_isize_extended() when extending the file size. - Fix highmem and page/folio access in compressed I/O paths by using the correct local mappings and page helpers. - Apply per-file $LXMOD permissions instead of mount masks when available, and prevent unprivileged writes to reserved $LX* attributes. - Update the NTFS maintainer mailing list. - Four small cleanups.
Sorry for sending this pull request last minutes. This branch missed the last
merge window and had been sitting in the for-next branch; I nearly forgot about it.
Bootconfig updates for v7.3:
- bootconfig: Support build-time command line rendering for embedded bootconfig
. bootconfig: render descendant keys when xbc_snprint_cmdline() root has a
value. Fix xbc_snprint_cmdline() to render descendant keys when the root
has both a value and subkeys, and treats empty subtrees correctly.
. bootconfig: render embedded bootconfig as a kernel cmdline at build time.
Add build-time pipeline using tools/bootconfig -C to render the embedded
bootconfig "kernel" subtree into .init.rodata as a cmdline string.
. bootconfig: clean build-time tools/bootconfig from make clean.
. bootconfig: add xbc_prepend_embedded_cmdline() helper.
Add helper to prepend embedded bootconfig cmdline into boot_command_line
early before parse_early_param().
. x86/setup: prepend embedded bootconfig cmdline before parse_early_param.
Wire early prepend helper in x86 setup_arch() so early_param handlers see
values from the embedded bootconfig. (So this feature is currently x86 only)
. bootconfig: skip runtime kernel.* render once prepended early.
Avoid duplicating "kernel" keys in setup_boot_config().
. init/main.c: use bootconfig_cmdline_requested() for the runtime opt-in.
Refactor setup_boot_config() to share bootconfig_cmdline_requested().
. Documentation: bootconfig: document build-time cmdline rendering.
Document CONFIG_CMDLINE_FROM_BOOTCONFIG usage, requirements, and precedence.

please pull the latest slab updates from: There's a semantic conflict with changes in char-misc that will break Rust build due to a change of kvfree_call_rcu() parameter type. In linux-next this was solved by this fixup applied as part of the merge commit of whichever of the trees is merged later: https://lore.kernel.org/all/[email protected]/ Thanks, Vlastimil - Addition of kfree_rcu_nolock() that can be used from contexts where spinning on a lock might be unsafe, such as a BPF program attached to an arbitrary function, or in NMI context. This complements the existing kfree_nolock() support. (Harry Yoo) - Runtime instead of compile-time slabobj_ext sizing. Avoids wasting memory when memory allocation profiling is compiled but not enabled, with initial partial support to also avoid wasting memory for objcg pointers when those are not needed, while profiling is enabled.

as anticipated, here is the second part of the I2C pull request for v7.3. I waited a little before sending it because I wanted to give the branch a few more days of testing after merging the Rust pull request. It contains a few small fixes and cleanups around probe error handling, resource management and a minor Rust cleanup. (I added this short introduction to the tag log, as I noticed you copied it from there in the past.) The branch is rebased onto your I2C part 1 merge commit. That should be all from I2C for v7.3. Thank you, Andi i2c for v7.3, part 2 Fixes and cleanups around probe error handling, resource management and a minor Rust cleanup. Drivers: - several drivers: drop duplicate IRQ error reporting - imx-lpi2c: improve probe initialization and error cleanup - mxs: fix DMA channel leak on probe failure - ocores: fix clock cleanup on resume failure - rcar: handle reset controllers without status support Muxes: - demux-pinctrl: fix OF node leak on allocation failure Rust: - mark trivial I2cAdapter reference-counting methods inline

The s390 cpuidle driver series adds a new driver under drivers/cpuidle/ and the corresponding MAINTAINERS entry. The driver was reviewed by Christian Loehle, and the whole series was acked by cpuidle maintainer Rafael J. Wysocki: https://lore.kernel.org/all/[email protected]/ The series also removes now unused generic arch_needs_cpu() hook: include/linux/tick.h | 3 - s390 updates for 7.3 merge window - Add a cpuidle driver with polling and enabled wait states using the existing CPU idle infrastructure and idle governor to improve latency for frequent sleep/wakeup cycles. Remove the obsolete tick delay heuristic and generic arch_needs_cpu() hook. Add the corresponding driver entry to MAINTAINERS - Add kCFI support using the generic support provided by Clang - Enable Clang CONTEXT_ANALYSIS for various architecture code and for char, PCI, CIO and virtio drivers. Add required lock annotations, exclude unsupported mm helpers and remove conditional PCI locking - Fix secure storage access exception handling and reintroduce DCACHE_WORD_ACCESS previously removed as a workaround - Fix cpum_cf perf crashes when CPUs are brought online while per-task events are active. Allocate and remove per-CPU counter data from CPU hotplug callbacks - Fix a deadlock when an s390dbf debug area is unregistered while one of its debugfs files is being written to - Fix MVIY_PERCPU() with binutils older than 2.39, where an assembler macro silently omitted an instruction needed to repair interrupted operations after CPU migration - Remove/replace cond_resched() calls which are no-ops with the supported s390 preemption models - Fix AP queue depth and maximum message length decoding according to the architecture. Current hardware is not affected, but future hardware could report values which were handled incorrectly - Reflect the configured CPU state in cpu_enabled_mask so deconfigured CPUs are not presented as available for onlining - Restore the vDSO GNU_EH_FRAME program header which was lost when the build switched to direct linker invocation, and mark it read-only - Add SCLP action qualifiers used by Spyre for card initialization, recoverable error and telemetry reporting - Move KMSAN interrupt flag helpers out of line to fix -Wstatic-in-inline build warnings - Use level-specific page table entry accessors for hugetlb entries and ptep_get() when accessing crashed kernel memory in kdump - Make forced AP bus rescans killable so that a user process blocked behind an ongoing scan can still be terminated with SIGKILL - Rework pkey ioctl error paths to remove duplicated cleanup code and avoid freeing error pointers - Allow the protected guest SWIOTLB buffer to be allocated outside the first 2GB. Also enable dynamic SWIOTLB growth and the coherent atomic pool fallback to improve I/O behavior when the initial pool is exhausted - Add program check statistics and spinlock contention tracepoints. Increase the lockdep chain capacity to keep lockdep enabled for complex code paths such as btrfs - Simplify IPL, trap and syscall code and remove the obsolete unistd_32.h generation entry
This is the second part of liveupdate changes for v7.3-rc1. The changes here depend on the work merged via Andrew's tree, so I waited for his pull request to go in. kho: make boot time huge page allocation work nicely with KHO Today allocation of gigantic pages in HugeTLB cannot work reliably with KHO: * HugeTLB allocates gigantic pages using memblock and autoscaling of KHO scratch accounts for these allocations. When gigantic pages occupy half of the memory of more, KHO fails to allocate its scratch memory. * After kexec handover, memblock allocations exclusively use KHO scratch that is not supposed to contain preserved memory. This essentially blocks preservation of HugeTLB with gigantic pages. Extend early memory pools available for KHO kernel with areas that are guaranteed not to contain preserved memory.
This is ksmbd server update pull request for v7.3-rc1. I add a description of Thanks! This contains a set of 142 SMB server updates focused on SMB2 command sequencing, SMB3 request replay and encryption, Apple Time Machine interoperability, protocol-compatibility fixes validated with smbtorture, security hardening, SMB Direct transport support, connection reliability, and other correctness improvements. New features: - Implement the SMB2 command sequence window. Enforce the credit-based MessageId range for each connection, rejecting out-of-window, duplicate, and wrapped sequence numbers. This prevents invalid requests and same-channel replays from being processed. - Add SMB3 request replay support. SMB3 clients may resend requests with SMB2_FLAGS_REPLAY_OPERATION after a channel disconnect when the original response was lost. Track the required channel and open state to safely handle durable CREATE replays and make oplock, lease, and lock replays idempotent, avoiding duplicate state changes and improving multichannel reconnect reliability. - Add opt-in Apple Time Machine support. Implement the AAPL negotiation and related Finder, stream, COPYCHUNK, sparse-file, CHANGE_NOTIFY, and RPC compatibility required for Time Machine shares, allowing macOS backupd to use ksmbd for backups. - Add per-share SMB3 encryption support. Allow individual shares to require SMB3 encryption by advertising SMB2_SHAREFLAG_ENCRYPT_DATA in TREE_CONNECT responses and rejecting unencrypted tree connects and plaintext requests for protected shares. - Add SMB Direct RDMA encryption support. Extend SMB Direct to support SMB3 encrypted payloads over RDMA, with transform negotiation and encryption/decryption for RDMA READ/WRITE. Other changes: - Parse and retain AppInstanceVersion contexts, enforce version ordering, close older active handles for newer takeovers, and reject invalid or unversioned opens according to the SMB2 semantics. - Accept durable reconnect requests that omit VolatileFileId when the persistent ID and reconnect context identify the handle, while continuing to reject explicit volatile-ID mismatches. - Fix SMB2/SMB3 protocol validation and security issues, including request offsets, file and object IDs, IPC responses, output buffer sizes, SMB3.1.1 binding validation, signing-required handling, durable handles, ACLs, maximal access, and security information. - Fix heap out-of-bounds accesses, use-after-free bugs, memory leaks, invalid pointer dereferences, and sensitive-data lifetime issues in authentication, Kerberos, preauthentication, sessions, connections, and module teardown. - Correct alternate-data-stream and named-stream handling, COPYCHUNK behavior, sparse-file and compression attributes, allocated-range queries, file trimming, duplicate extents, DOS attributes, snapshots, normalized names, and partial information responses. - Fix locking, lease, oplock, durable reconnect, async request, and CHANGE_NOTIFY races, including deferred-lock rollback, parent directory lease notifications, and connection teardown lifetime bugs. - Fix SMB3 encryption handling for compressed requests, expired encrypted sessions, interim responses, bound multichannel connections, and decryption failures. - Fix SMB3 multichannel session lookup and session state transitions so changes are scoped to the correct bound connections and cannot revive connections that are already shutting down. - Fix DACL access checks so ACE walks are bounded by the declared DACL size, preventing data beyond the DACL boundary from being interpreted during access validation. - Fix session accounting and lifetime issues, including session counter updates during publication and removal, session leaks on registration failure, and procfs creation diagnostics. - Improve TCP connection reliability by enabling TCP keepalive for accepted connections and preserving TCP timers for kernel sockets, preventing silent peers from holding connections indefinitely. - Fix smbdirect RDMA cleanup ordering for completion queues, QPs, child sockets, and listener locking. - Improve async response framing, multi-iovec signing, RPC pipe status handling, and ksmbd procfs monitoring for server, share, connection, session, and open-file state. - Remove the obsolete DES crypto header and Kconfig dependency now that NTLMv1 support has been removed. - Update the ksmbd repository URL in MAINTAINERS and add an additional KSMBD reviewer.

This is exfat update pull request for v7.3-rc1. I add a description of Thanks! This contains a set of nine exfat fixes covering shared writable mappings, entry error handling, allocation cleanup, FITRIM bounds, and locking: - Fix valid_size extension over shared writable mappings by lazily zeroing page-cache gaps and ensuring racing stores cannot be overwritten or extend beyond valid_size. - Clean up partially written directory entries on add-entry failure and safely free new directory clusters. - Free a newly allocated directory cluster when zeroing it fails. - Write the destination entry before removing the source entry during rename, preserving the source if the destination write fails. - Keep FITRIM within the requested range, even when the free-space search wraps around the allocation bitmap. - Fix truncated FS_IOC_GETFSLABEL results by passing the destination buffer size in bytes to the UTF-16-to-NLS conversion. - Fix overflow in the cluster-to-dentry calculation, which could cause readdir to stop early on large volumes. - Replace the per-inode truncate_lock with inode_lock, using shared locking in bmap to serialize against concurrent truncation. - Update the exfat mailing list address in MAINTAINERS.
firewire updates for v7.3 This update includes error checks, a potential bug fix, and KUnit tests. Sreeraj S Kurup addressed an error case when generating the contents of the configuration ROM with parameters supplied by in-kernel implementations such as unit drivers. Some error checks were added to handle failures in this path. Abdun Nihaal identified a potential memory leak when an invalid self-ID sequence causes an error while building the internal node tree. KUnit tests have been added to trigger this case. This memory leak has existed since the first commit and has now been fixed.
Please consider pulling the following changes in perf tools for v7.3.
Thanks,

perf tools updates for v7.3
perf c2c:
- Add 'function view' in perf c2c report TUI (switched by pressing 'TAB'
in the cacheline view) to organize samples around functions rather than
cachelines in 3-level hierarchy:
Level 1: Read-side function (sorted by estimated Cycles %)
Level 2: Contending writer functions (sorted by Store count)
Level 3: Shared cacheline addresses

python module support:
- Extend "perf" python module so that it can be fully functional. The goal
is to run scripts directly, not by 'perf script' command. This would give
better performance as well as more control to build standalone programs
with UI.
- Add LiveSession helper (perf_live.py) to enable live event collection
directly from Python using perf.evlist and perf.parse_events.
perf stat:
- Add --hide-zero-events option to suppress zero-count events.
- Reject conflicting --field-separator and --json-output options.
- Fix duplicate event output with --for-each-cgroup.
perf sched latency:
- Add -H/--histogram and --hist-mode (log|linear) options to show scheduler
wait latency histograms.
- Add --time option to filter analysis by time span in 'perf sched latency'.
ARM CoreSight:
- Synthesize callchains for instruction samples from CoreSight trace
using thread stack ('--itrace=g...').
- Support call indentation ('perf script -F +callindent') to display call
depth hierarchy on branch samples.
- Decode ETE (Embedded Trace Extension) exception packets.
Build system:
- Add 'make install-build-deps' target to install required packages.
- Parallelize JSON and metric pre-computation in jevents.py for faster builds.
Vendor event/metric updates:
- Add Intel Nova Lake events and update tables for existing models.
- Update AMD Zen 5 and Zen 6 core events.
- Update Arm64 Tegra410 metrics and PowerPC hcalls.
Internal changes and fixes:
- Harden trace-event and synthetic event parsing against corrupted data.
- Fix unwinding of multi-threaded processes in libdw unwinder.
- Fix memory leaks in various commands and python bindings.
- Speed up 'perf test' shell tests.

Modules changes for 7.3-rc1 - Remove unnecessary module::args. Nowadays, no parameter-handling code points into the module::args buffer. The last user of module::args in xtensa/simdisk is updated and the data is then removed. - Add Rust support for boolean parameters. This will initially be used by the Rust null block driver. - Fix clearing the current charp parameter value when setting a new one fails due to an allocation failure. - Improve the debugging code for kmod (request_module()) duplicates. Fix a potential use-after-free when waiting on a duplicate request and make several general improvements to the code. - Fix the symbol size returned when looking up a data symbol through kallsyms. - The remaining changes are smaller fixes and cleanups.
This message is in MIME format. The first part should be readable text,
while the remaining parts are likely unreadable without MIME-aware tools.
Linus,
point of view, there's a new header file include added into one of the
ACPI driver files. This doesn't affect existing ACPI-enabled
architectures.

RISC-V updates for v7.3
- Add initial definitions and discovery for the Smcsrind, Sscsrind,
Smcntrpmf, Ssccfg, Smcdeleg, Zicclsm, Ziccamoa, Ziccif, Ziccrse,
Za64rs, and Ssqosid RISC-V ISA extensions
- Improve the RISC-V update_mmu_cache_range() implementation by using
flush-by-ASID, enabling performance improvements on
microarchitectures that support related optimizations; and by taking
advantage of the Svinval RISC-V ISA extension on microarchitectures
that support it
- Shrink CFI shadow stack allocation further (to 512MB) to save
virtual address space (and physical memory on systems with strict
overcommit policies)
- Add initial CPU context switch support for QoS tagging (Ssqosid)
- Change our vector misaligned access speed test code to be
synchronous, avoiding a bunch of bugs related to unnecessary
asynchronicity
- Enable ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V to help with ACPI
table debugging (similar to ARM64 and x86)
- Extract vDSO section offsets at build time, rather than run time, to
avoid the boot time overhead
- Use assembler directives to control the use of instructions from the
RISC-V ISA extensions Zacas and Zabha, rather than compiler -march
flags that could affect the whole kernel (similar to ARM64)
- Add a kselftest for kprobes support for the c.jal instruction on
RISC-V
- When UEFI runtime services are available, use them to restart and
power off
- Fix ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V by adding a missing
include file to the ACPI code
- Move contiguous DMA memory reservation later in the boot, to ensure
that the correct global and per-node pools are allocated when
CONFIG_CMA_SIZE_PERNUMA is enabled
- Disallow probes on breakpoint handlers to avoid recursing
indefinitely into do_trap_break()
- Patch the compat vDSO during runtime alternatives processing, not
only the standard vDSO
- Remove some leftover XIP support elements missed by commit
9b3a2be84803 ("riscv: Remove support for XIP kernel")
- Fix broadcast timer switching in ACPI LPI power states by
implementing a RISC-V version of arch_get_idle_state_flags()
- Miscellaneous fixes, including: vDSO makefile simplification;
marking our default_power_off() as __noreturn; error path fixes in
the PMU SBI perf driver; RISC-V extension capitalization
consistency; the use of BIT() macros in one of our include files;
and some documentation fixes
Hi, This PR improves observability with Landlock tracepoints support, which required some refactoring for dedicated domain types and common helpers shared with audit code. A LANDLOCK_RESTRICT_SELF_NO_NEW_PRIVS flag is also added to improve process-wide domain enforcement consistency. Whiteout files are now correctly handled and tested, and a few other fixes complete this PR. with your master branch. Most kernel changes have been tested in the latest linux-next releases for some weeks, and I recently updated commit messages to reflect latest reviews. Test coverage for security/landlock is 91.6% of 2571 lines according to LLVM 22, and it was 91.8% of 2357 lines before this PR. Regards, Mickaël -- Landlock update for v7.3-rc1
This is the main drm pull request for 7.3-rc1. This unusally ends with a backmerge, the tree has been sitting on 7.2-rc2 and we didn't do any backmerges and the conflict numbers were extra high due to code movement, so I decided to do a 7.2 backmerge to use our drm-tip merges. On the bright side, this means there are only two minor rust conflicts with your tree. This has a shared tree with driver-core for some rust i/o reworks, and some perf exports. I'll also note I didn't get an msm pull this round, which makes me suspect something ate it somewhere, so it might arrive later in the week. Highlights: - dmemcg eviction support is good for low VRAM things like Steam Machine - AMD adds gfx6-8 modifier support for older GPUs that enables a bunch of wayland stuff - i915/xe has some new hw support but also a lot of display refactoring Let me know if there any problems, or if you really don't like the backmerge, it just seemed like a lot of conflicts to resolve that we'd already resolved. We are moving towards a new -next procedure as well where drm/misc/i915/xe and hopefully amd will start to be merged into a single for next tree with all out -next/-fixes trees in it, to lighten the load on others.

Hi Andi, First pull request from the rust-i2c tree for you. Thank you. Igor i2c: rust: mark I2cAdapter methods as inline A single cleanup for the Rust I2C abstractions, targeting 7.3. `I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around `i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own symbols in the build. Mark them `#[inline]` so they get folded into their callers instead. Signed-off-by: Igor Korotin <[email protected]>
Hi, this is summer edition of btrfs changes, smaller than usual. Yet, there are performance improvements in various areas or for specific workloads and some notable changes like removing space cache v1 code or mount option reduction. User visible changes: - free space v1 disabled by default; the v2 (free space tree) is mkfs default since 5.15, filesystems with v1 still work but could be slightly slower due to lack of block group caching - mount option 'rescue=usebackuproot' requires read-only mount, it's too risky to allow writable mount - remove standalone mount option 'usebackuproot', deprecated in 5.9 - preserve constraints of NODATASUM and NODATACOW when chattr and mount options may change the attributes - remove arbitrary limitation of 4KiB for page size when allowing block sizes smaller than page - print messages when pinned block groups affect swap activation Performance improvements: - use iomap bounce buffer for direct io instead of a fall back to buffered io; past correctness vs speed trade-offs dropped performance to ~50% of theoretical maximum, now it's ~95%, effectively doubled - replace xarray with local LRU list for tracking inhibited extent buffers, restored performance to pre-inhibition state (relatively ~3x) - remove unnecessary 1 jiffy delay in "non-SSD" mode with multiple logging tasks, decrease latency, throughput increased ~5x on sample workload - skip hole detection during full fsync for files without holes and lots of extents, reduce run time ~5x on sample workload (microsecond ranges) - reduce locking around extent readahead so it does not slow down other tasks using an overlapping range - enhance extent buffer allocation modes to allow NOWAIT semantics in some cases Notable fixes: - write-protect folios during writeback, prevent concurrent mmap and compress/checksumming/etc undesired interactions - in zoned mode, handle transient overcommit full instead of going read-only - fix possible deadlock between defragmentation and delayed allocation reservations - handle remaining iputs at umount time - fix lockdep warning between device scan locking and log mutex - add workaround for degenerate RAID56 device count modes (2 and 3) not supported by the parity calculation library - restore check that subvolume is not read-only when changing ACLs - retry reading verity data colliding with up-to-date status changes Core: - simplify raid56 stripe handling by using contiguous virtual allocations - in zoned mode, fix various metadata write issues in writeback or unmount - space reservation fixes - remove unused data structure members - more auto-freeing conversions - error pointer values are printed using %pe format
NFSD 7.3 Release Notes Jeff Layton contributed CB_NOTIFY support to NFSD's NFSv4.1 directory delegations. The server used to recall a delegation as soon as the directory changed. NFSD now watches delegated directories through fsnotify and reports adds, removes, renames, and directory attribute changes, carrying the filehandle and attributes of the affected entry, so clients can keep their caches. Some of the NOTIFY4 flags come from RFC 8881bis. Jeff Layton also continued the netlink work that started in v7.2. A new server-stats-get operation reports what /proc/net/rpc/nfsd publishes, plus NFSv4 callback counts, and SUNRPC now keeps its per-procedure call counts per network namespace, so a container sees its own numbers. nfsstat reads all of this over netlink, with a procfs fallback for older kernels. SUNRPC's service thread pool mode selection is gone. Pernode is the right choice on any host we run today, so the auto, global, and percpu modes have been removed. A single-node host still gets one pool. A multi-NUMA host now gets a pool per node. sunrpc.pool_mode accepts the old names but no longer selects anything. The rest is bug fixes, clean-ups, and small optimizations: an async COPY offload rework from Jeff Layton, more use-after-free fixes in the NFSv4 state revocation paths, percpu counter contention removed from the reply cache and IO accounting, and a long list of hardening fixes from Chris Mason. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.3 NFSD development cycle.

cycle. It's been busy. This cycle I squirted out 1250 "added-to-mm" emails. In the previous cycle it was 920. So lots of material. 500 patches here, nearly 200 lined up for next week. I don't enjoy typing up those patch series summaries, so I haven't been doing them well. This time I recruited Gemini to draft many of the bullets and then I did a review/edit pass. I think the result is better(?). I'm seeing no merge conflicts at this time.

For some reason lots of people have been working on the page_owner code this cycle. - The 4 patch series "mm: convert to walk_page_range_vma() to eliminate find_vma()" from Kefeng Wang simplifies and accelerates the page walking library function. - The 3 patch series "mm/migrate: preparatory cleanups for batch copy and offload" from Shivank Garg implements cleanups in the migration code. - The 4 patch series "mm/page_owner: add per-fd filter infrastructure for print_mode and NUMA filtering" from Zhen Ni provides per-fd filtering to page_owner in order to reduce the sometimes vast amount of output it can produce. - The 19 patch series "mm: Refactor bootmem gigantic hugepage allocation" from Muchun Song is a "set of fixes and preparatory cleanups around bootmem HugeTLB handling, sparse initialization ordering, and related vmemmap setup". - The 4 patch series "mm/zsmalloc: reduce lock contention in zs_free()" from Wenchao Hao reduces lock contention in zs_free(), which dominates the unmap path under memory pressure on Android (LMK kills) and on x86 servers running zswap-heavy workloads. Up to 1.83x improvement in microbenchmarking. - The 2 patch series "move alloc_tag.c file under mm/" from Suren Baghdasaryan does that. - The 6 patch series "samples/damon: handle damon_{start,stop}() failures" from SJ Park fixes improper handling of damon_start(), damon_stop(), and damon_call() failures across DAMON sample modules to prevent potential memory leaks, operation disruptions and use-after-free bugs. - The 11 patch series "mm/damon/sysfs: kobject_del() directories that users can create/remove" from SJ Park resolves an issue where delayed sysfs directory removal under CONFIG_DEBUG_KOBJECT_RELEASE causes creation failures due to duplicate directory names by adding missing kobject_del() calls before creating new directories. - The 3 patch series "mm: cleanup clear_not_present_full_ptes()" from David Hildenbrand cleans up the core pte handling code. - The 3 patch series "selftests/damon: misc fixes for test bugs" from Kunwu Chan fixes several bugs in the DAMON selftests. - The 2 patch series "selftests/damon: fix memcg_path staging handling" from Cheng Nie fixes a bug in _damon_sysfs.py for damos_filter memcg_path setup, and adds a test case for it in sysfs.py. - The 2 patch series "selftests/damon: test kdamond refresh_ms" from Ruslan Valiyev introduces selftest coverage for DAMON's refresh_ms sysfs feature by updating the test control module and verifying that scheme stats update automatically without manual intervention. - The 5 patch series "mm/damon: five misc fixups" from Akinobu Mita contains miscellaneous DAMON fixups. - The 2 patch series "mm/damon/core: detect internal variation above max_nr_regions/2" from Jiayuan Chen fixes DAMON's region splitting behavior when region counts exceed half the maximum budget by dynamically scaling down the split fraction as the limit approaches, preventing large regions from staying un-split, and adds corresponding KUnit test coverage. - The 6 patch series "mm: preparatory patches for PMD level swap entries" from Usama Arif refactors and cleans up PMD softleaf helpers, call sites, and architecture flags to lay the groundwork for a follow-up series that introduces PMD page table swap entries. - The 11 patch series "mm/damon: update, optimize, and clean up doc, tests, and code" from SJ Park updates DAMON design and ABI documentation, expands unit and selftest coverage, optimizes damon_commit_target_regions(), and cleans up recently added sysfs interface code for better readability. - The 2 patch series "mm/vmpressure: reduce CPU, memory and code overhead on cgroup v2" from Usama Arif optimizes vmpressure() by skipping unnecessary work on cgroup v2 for userspace event notifications and refactors v1-only eventfd handling into mm/memcontrol-v1.c to reduce memory overhead and code complexity. - The 10 patch series "selftests/mm: refactor pkey helpers and fix mmap error handling" from Hongfu Li refactors pkeys shared tracing and assertion helpers into a common file, unifies protection key selftests to use consistent diagnostic logging and assertions, and enforces standardized MAP_FAILED return checks for mmap() calls across the tests. - The 18 patch series "mm/damon: optimize out nr_accesses_bp" from SJ Park replaces the error-prone, continuously updated nr_accesses_bp field in damon_region with an on-demand moving sum function (damon_nr_accesses_mvsum()), reducing structure memory overhead and avoiding state corruption bugs. - The 6 patch series "Open HugeTLB allocation routine for more generic use" from Ackerley Tng decouples HugeTLB folio allocation from VMA dependencies by introducing hugetlb_alloc_folio(), enabling subsystems like guest_memfd to allocate HugeTLB folios without standard VMA reservations or pseudo-VMAs. - The 3 patch series "mm/damon: provide pseudo moving sum probe_hits" from SJ Park integrates DAMON's probe_hits attribute counter into the pseudo moving sum infrastructure, enabling real-time, online monitoring without waiting for full aggregation intervals. - The 18 patch series "mm: Some cleanups for page allocator APIs" from Brendan Jackman simplifies and refactors the page allocator entry points and flags by unifying allocation paths, adding internal alloc_flags arguments, and eliminating redundant __ prefixed alloc_pages variants. - The 5 patch series "Fix incorrect access of hugetlb pte entries" from Dev Jain enforces the consistent use of huge_ptep_get() instead of ptep_get() for HugeTLB entries and fixes an unaligned address issue in arm64's huge_ptep_get() implementation. - The 8 patch series "mm/damon: validate all parameters in the core" from SJ Park consolidates parameter validation into the DAMON core specifically within damon_start() and damon_commit_ctx() to centralize error checking, eliminate caller-side redundant checks and to improve maintenance efficiency. - The 3 patch series "tools/mm/page_owner_sort: fix filtering and cleanup issues" from Yichong Chen renames is_need() to filter_record() for clearer return semantics, fixes per-record allocation memory leaks and bounds output copies in search_pattern() to address an existing buffer issue. - The 4 patch series "memcg: bail out reclaim when memcg is dying" from Jiayuan Chen mitigates a system-wide stall which occurs when a cgroup is removed while one of its memory control files is doing synchronous reclaim. - The 5 patch series "mm/memory-failure: add panic option for unrecoverable pages" from Breno Leitao introduces an opt-in vm.panic_on_unrecoverable_memory_failure sysctl that immediately panics the kernel on unrecoverable memory errors in kernel-owned pages to preserve error context and prevent delayed, silent data corruption. - The 11 patch series "mm/damon: refactor damon_{start,stop,commit}() for simple error handling" from SJ Park refactors the DAMON core API functions to guarantee that all contexts are fully stopped when damon_start(), damon_stop(), or damon_commit() fail, eliminating the need for complex and error-prone caller-side cleanup code. - The 5 patch series "Keep tail page private zero at free and folio split" from Zi Yan adds checks to ensure tail_page->private is zero when freeing compound or high-order pages and when promoting tail pages during large folio splits. By validating these fields at free and split time, it allows the removal of redundant private field clearing inside prep_compound_tail(). - The 4 patch series "mm: drop redundant lru_add_drain in anon folio reuse paths" from Barry Song eliminates redundant lru_add_drain() calls in wp_can_reuse_anon_folio() and do_swap_page() to reduce LRU lock contention and system overhead. By validating folio refcounts against the LRU cache before draining and removing unnecessary drains in the swap path, it achieves up to a 30.5% reduction in drain calls during heavy swap workloads. - The 3 patch series "mm: clean up folio LRU and swap declarations" from Jianyue Wu reorganizes folio LRU and swap code by relocating page-cluster state to mm/swap_state.c, renaming mm/swap.c to mm/folio.c, and moving MM-internal reclaim declarations into mm/internal.h. - The 15 patch series "userfaultfd: working set tracking for VM guest memory" from Kiryl Shutsemau adds userfaultfd support for tracking the working set of VM guest memory, so a VMM can identify hot pages and reclaim cold ones to tiered or remote storage. - The 10 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 2)" from David Hildenbrand removes the remaining pieces of CONFIG_HAVE_BOOTMEM_INFO_NODE, performing some smaller cleanups around freeing of reserved vmemmap pages on the way. - The 7 patch series "mm/damon: update probe hits for runtime parameter commits" from SJ Park ensures that DAMON's probe_hits attribute counter is properly updated when monitoring intervals are changed at runtime, matching the behavior of nr_accesses. To achieve this, it refactors and renames existing helper functions for shared use, applies the updates to probe_hits, and handles edge cases in damon_probe_hits_mvsum() to maintain measurement accuracy. - The 3 patch series "KSM: performance optimizations for rmap_walk_ksm" from xu xin resolves a severe KSM reverse-mapping performance bottleneck where thousands of split VMAs sharing a single anon_vma cause extended lock contention. By adding an interval-filtering check during the rmap walk, it reduces worst-case anon_vma lock hold times from over 500ms down to under 2ms, preventing application freezes and latency spikes under memory pressure. - The 3 patch series "mm: split a couple of headers from internal.h" from Mike Rapoport splits declarations related to mm_init, memblock, vmalloc and sparse into new headers. - The 2 patch series "KSM: use linear_page_index in collect_procs_ksm()" from xu xin applies the interval tree optimization from rmap_walk_ksm() to collect_procs_ksm() to avoid iterating over non-matching VMAs during KSM memory error handling. It hoists loop-invariant address initialization and restricts the anon_vma_interval_tree_foreach walk to a targeted page offset range, reducing redundant checks and improving lookup efficiency. - The 3 patch series "selftests/mm: avoid false failures in hugetlb and KSM tests" from Sayali Patil fixes issues in the hugetlb and KSM MM selftest categories that can report failures when the prerequisites for the tests are not satisfied. - The 19 patch series "mm/damon: introduce data attributes only monitoring" from SJ Park introduces attribute-weighted region management in DAMON, allowing users to prioritize specific data attributes (such as page sizes or cgroups) over or instead of access monitoring. By assigning weights to attribute probes, DAMON can completely disable access tracking and adjust monitoring regions based on weighted probe-hit counters to optimize monitoring quality for attribute-focused workloads. - The 8 patch series "mm/hmm: Add mmap lock-drop support for userfaultfd-backed mappings" from Stanislav Kinsburskii extends hmm_range_fault() to support userfaultfd-backed regions by allowing the mmap lock to be dropped during fault handling via a new hmm_range_fault_locked() helper. By accepting a locked pointer and signaling retry status when lock release occurs, it enables page fault resolution in userfaultfd regions while preserving backward compatibility for existing callers. - The 33 patch series "mm: make VMA page offset handling more consistent" from Lorenzo Stoakes cleans up and standardizes how vma->vm_pgoff is accessed and manipulated across file-backed and anonymous mappings in the kernel. It introduces dedicated helper functions such as vma_start_pgoff(), vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while renaming rmap interval tree helpers to better reflect their functionality. These changes establish a cleaner foundation for future work that will unify virtual page offset indexing for all anonymous and CoW'd folios. - The 3 patch series "mm: handle device-private PMDs in walk callbacks" from Usama Arif addresses kernel panics and state corruption caused by MM walk callbacks reaching non-present device-private PMD swap entries created during HMM migrations. It ensures that functions which acquire pmd_trans_huge_lock() properly recognize device-private PMDs instead of assuming a present THP or a standard migration entry. - The 5 patch series "mm/rmap: Refactor try_to_unmap_one" from Dev Jain refactors try_to_unmap_one by modularizing Hugetlb, anonymous-lazyfree, and anonymous-swapbacked logic into dedicated functions, laying the structural groundwork for batched anonymous large folio unmapping. - The 4 patch series "Docs/ABI/damon: sysfs ABI document fixes and additions" from Song Hu fixes typos and fills in missing entries in the DAMON sysfs ABI document. - The 10 patch series "dax/kmem: atomic whole-device hotplug via sysfs" from Gregory Price introduces an atomic sysfs state attribute and supporting DAX/MM infrastructure to prevent userland races when offlining and removing entire memory regions. By adding an unplugged state alongside standard online modes, it enables whole-device atomic hotplug control while preserving backward compatibility. - The 13 patch series "mm: convert more vm_flags_t users to vma_flags_t" from Lorenzo Stoakes continues transitioning the kernel from the deprecated vm_flags_t type to vma_flags_t across core memory management infrastructure. It replaces legacy type usage in core functions such as do_mmap(), unmapped area allocation, mm->def_vma_flags, and VMA operations like mlock, mprotect, and mremap. - The 2 patch series "Two small patches to clean up mm/mm_slot.h" from xu xin refactors mm_slot.h by introducing mm_slot_remove() to unify duplicate slot deletion sequences in khugepaged and KSM. It also adds code documentation explaining why mm_slot_lookup and mm_slot_insert must remain as preprocessor macros rather than static inline functions. - The 10 patch series "mm/damon/core: hide core-private struct fields" from SJ Park cleans up DAMON core structures by consistently marking internal-only fields with private: comment tags to prevent improper direct access from outer layers. It enforces encapsulation across core structures including damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to interact through approved access APIs instead of exposing raw struct members. - The 6 patch series "mm/damon: unurgent fixes for infinite loop, NULL de-ref and races" from SJ Park addresses potential infinite loops, NULL dereferences, and race conditions identified in DAMON. It fixes an infinite loop triggered by extreme user configurations, a NULL pointer dereference within unit tests and minor monitoring accuracy degradation caused by subtle runtime races. - The 2 patch series "mm/page_alloc: fixes for free_pages_nolock() on RT/UP" from Brendan Jackman fixes an NMI safety flaw in __free_frozen_pages() where freeing pages on non-SMP or PREEMPT_RT kernels can bypass can_spin_trylock() checks via non-PCP or isolated migration paths. It also resolves potential kernel crashes and privilege escalation risks triggered when BPF tracing runs in NMI context alongside memory hotplug or large allocation frees. - The 4 patch series "mm/page_alloc: couple of followups for recent cleanups" from Brendan Jackman cleans up and updates page allocator nomenclature, documentation, and debug assertions. It aligns internal FPI_ flags with the public "nolock" naming convention, removes outdated internal implementation details from high-level page allocator comments, and eliminates obsolete VM_BUG_ON() assertions in allocation paths. - The 3 patch series "mm/mseal: further cleanups" from Lorenzo Stoakes refactors and simplifies the mseal implementation by clarifying API boundaries and removing unnecessary code complexity. It replaces generic do_mseal() usage outside the syscall with a dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO, eliminates mm_struct parameters to enforce that sealing applies only to current->mm, and streamlines overall logic and comments with no functional changes intended. - The 4 patch series "mm/vmscan: fix swappiness=max and clean up per-node proactive reclaim" from Ridong Chen resolves reclaim behavior bugs and cleans up function parameters across memory reclaim paths. It fixes swappiness=max in both standard reclaim and MGLRU so unswappable anonymous memory no longer falls back to evicting page cache, ensures reclaim_store() returns accurate error codes instead of collapsing all failures into -EAGAIN, and removes the obsolete gfp_mask parameter from __node_reclaim(). - The 6 patch series "mm: mincore: misc cleanups" from Kefeng Wang cleans up and simplifies the mincore code. Most importantly, it removes the historical special behavior that always reports VM_PFNMAP pages as non-resident. - The 2 patch series "mm/huge_memory: drop dead split helper variants" from Kiryl Shutsemau implements two trivial cleanups in the folio split API. - The 7 patch series "mm/damon: fix uninitialized DAMOS field and kunit exec expectation bugs" from SJ Park resolves minor operational and testing bugs in DAMON identified by Sashiko. It initializes the damos->last_applied field to prevent occasional efficiency degradation and fixes invalid memory accesses in DAMON KUnit tests during test failure handling. - The 3 patch series "cleanup for stable_page_flags()" from Jinjiang Tu cleans up and refactors stable_page_flags() used by /proc/kpageflags without altering functionality. It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag bits, converts folio-specific flag checks to standard folio_test_*() helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling. - The 3 patch series "Batch unmap of uffd-wp file folios" from Dev Jain extends batched folio unmapping support to file folios within userfaultfd write-protect (uffd-wp) VMAs by adding batching capabilities to pte_install_uffd_wp_if_needed(). This removes special-case restrictions on uffd-wp VMAs in try_to_unmap_one(), significantly simplifying the function's control flow and complexity. - The 3 patch series "mm/early_ioremap: clarify and clean up early_ioremap_reset()" from Sang-Heon Jeon clarifies and cleans up the architecture-specific usage of __late_set_fixmap() and __late_clear_fixmap() after early_ioremap_reset(). It adds explicit documentation regarding when early_ioremap_reset() must be called and removes redundant macro definitions and reset calls in the RISC-V and ARM64 architectures. - The 4 patch series "mm: fix reclaim storms in defrag_mode" from Johannes Weiner addresses severe performance regressions, swap storms, and spurious OOMs caused by vm.defrag_mode=1 under high memory pressure in Meta production. It updates the page allocator slowpath so non-movable allocation requests actively trigger direct reclaim and direct compaction at pageblock_order scale, allowing them to claim whole pageblocks rather than spinning unproductively. - The 2 patch series "zram: lockmap tweaks" from Sebastian Siewior optimizes and fixes lockdep tracking for zram devices by consolidating per-entry lockmaps and isolating lock classes across multiple instances. It reduces memory overhead by replacing per-entry lockdep_map instances with a single map per struct zram, and assigns a dynamic lock_class_key to each instance to prevent false deadlock reports when different zram devices are backed by distinct filesystems.
VFIO updates for v7.3-rc1 - Add nv_falcon vfio selftest driver. The Falcon is a general-purpose microcontroller embedded within NVIDIA GPUs, presenting a relatively simple DMA programming interface. This adds another selftest target for vfio-pci with real DMA transfers. (Rubin Du, Alex Williamson) - Add allocation assertion helpers to vfio selftests and use them to avoid variable length arrays and the compiler errors they generate. (Alex Mastro) - Fix use-after-free hazard where an init path error in MSI support leaves a stray pointer that can later be reused or double-freed. (Xiang Mei) - Fix previous refactor of PCI BAR mappings to honor non_mappable_bars flag, which otherwise generates a warning when trying to pci_iomap() a 256TiB BAR on ISM devices on s390. (Farhan Ali) - Add igb vfio selftest driver. Like nv_falcon, this provides another target for DMA testing with vfio selftests, but importantly this driver supports both physical 82576 NICs and the emulation model in QEMU. This therefore enables a vfio selftest vector with no physical hardware requirements. (Josh Hilke, Alex Williamson) - Mark selftest fixture objects __maybe_unused to accommodate builds with clang -Wunused-but-set-global. (David Matlack) - Add error recovery for vfio-pci devices on s390x. This expands devices which expose the existing error eventfd and introduces a device feature for reporting firmware defined error state information to the user, allowing recovery through hypervisor channels. (Farhan Ali)
One of the "small improvements all over the place" releases for us. It's hard to draw any direct comparisons because summer vacations disrupted our patch processing (and presumably - generation) quite a bit. Quick and dirty count suggests we (Paolo and I) merged a very similar number of net (632) and net-next (648) patches. This is not telling the full story either because 1/3 to 1/2 of the net-next patches also *seem* like AI-driven low priority fixes, cleanups and clarifications. We are completely overwhelmed, of course. The glimmer of hope is that we secured sufficient LLM budget and access (thank you Meta!) to run reviews with multiple frontier models on each patch. This eliminates some hallucinations. That said, in terms of review, the LLMs can only do so much. The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts etc.) have always been racy, and now LLMs don't let us ignore that. I expect our direction for the next release will be to tweak the reviews a little bit more, but start shifting focus to letting the LLMs take care of the busy work - managing patchwork, automating common process complaints, editing commit messages, and maybe applying patches which already got "reviewed-by" tags from people we trust... Enough blabber. Returning to this PR - you will see these conflicts: - trivial in MAINTAINERS, remove EHEA - trivial in include/linux/pci_ids.h, keep both - wifi/mt76 - keep the lockdep and the comment, rest it obvious https://lore.kernel.org/[email protected] Networking changes for 7.3. Core & protocols
soc: drivers for 7.3 The SoC driver changes once more consist of many small fixes and cleanups, that are to a large part the result of automated testing. On platform specific drivers, this includes SoC specific code for xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung, rockchip, renesas, ixp4xx. In firmware drivers, we see a similar picture for SCMI and qcomtee. Aside from these, we see actual new hardware support in a few areas: - The Apple platform gets a new driver for low power states - Updates to Qualcomm platform drivers add several new hardware specific features and additional SoCs. - Amlogic SoC support for A1 and T7 is added - The Mediatek MMSYS driver is refactored as a cleanup.
soc: devicetree updates for 7.3 There are two new mystery SoCs with very little public information about them so far, Qualcomm's Cortex-A78C based "Shikra" and Altera's Cortex-A720 based Agilex72 SOCFPGA. We have also gained support for a couple of SoCs from the 2023/2024 timeframe that have been in the making for a while: - The Apple platform gains support for M3 Pro, Max and Ultra SoC, following the basic M3 support from 7.2. - Samsung Exynos 1580 is a high-end mobile phone SoC from 2024 - Canaan K230 is a RISC-V based 64-bit AI SoC, based on the earlier K210 chip - Sophgo SG2000 is a mixed Arm/RISC-V chip that was already supported using the Arm core but is now also added for RISC-V along with several other variants of the cv18xx series In terms of newly added machines we have reference platforms for all the chips above, plus - only four 32-bit Arm boards: two older phones and two older industrial/embedded boards; using Allwinner, Qualcomm and Rockchip SoCs - Three laptops und three phones using Qualcomm SoCs - Ten 64-bit Rockchips based single-board computers, along with one NAS box and a game console. - Seven industrial/embedded boards and modules using NXP i.MX8/9 SoCs. - A Lenovo desktop box based on NVIDIA Jetson Xavier NX - A few more single-board computers based on Allwinnner A133, Spacemit K1 and TI AM62. As usual, there is a constant stream of minor cleanups and fixes towards addressing the 'dt-check-style --mode strict' warnings, and everyone is expected to address those warnings for new submissions now.
soc: defconfig updates for 7.3 Just the usual updates to the main defconfig files as well as the omap2 specific one, to enable more loadable modules for better default hardware support.
soc: Arm platform updates for 7.3 The 32-bit Arm platforms are a bit more interesting this time: I refresh= ed an earlier series to mark code as deprecated that does have the tendency of getting in the way of cleanups and new features but has close to zero users. Among these are: - 22 of the remaining 28 legacy board files that predate the current devicetree based descriptions, using old chips from Intel and Marvell. The remaining six board files are for TI OMAP1 and Samsung s3c64xx chips and all still have known users. - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25 machines based on these. These all use devicetree but the CPU support causes disproportional work. Most of them are just reference boards, the notable exceptions being the Nokia N800/N810 tablet and the Buglabs BUG platform. - be8, be32, oabi and iwmmxt userspace binaries, which were mostly associated with the platforms now scheduled for removal and are increasingly problematic to support with modern toolchains. Nothing is actually removed at this point, to ensure that any remaining users continue to have the 7.3-LTS for a while longer. Patches for removal are currently being tested. Other updates include a continued work to convert GPIO number based interfaces to descriptors, a patch to restore little-endian mode on the one Arm platform (ixp4xx) that only worked in big-endian mode recently, and some minor cleanups and bugfixes.
This one is again a little over 1000 non-merge commits, from 263
individual authors, with Qualcomm, NXP and Rockchip devicetree
files making up a majority of the changes. The new SoCs this
time are mostly a bit older, these include Apple M3 Pro/Max/Ultra,
Samsung Exynos 1580, Canaan K210, Sophgo SG2000 and the new
Qualcomm Shikra and as well as Altera Agilex72.
A small but noteworthy change is the deprecation of a number of
older 32-bit Arm platforms that were getting in the way.
For this release, nothing is actually being removed, but my
current testing has shown hundreds of now orphaned drivers that
can be removed along with those platforms.
The long-running devicetree cleanups are slowly getting to the
point of fixing known dtc compiler warnings and being able to
enforce this better for new contributions.

All commits have been in linux-next; two signed tags for "software node
fw_devlink support" and "Rust I/O type generalization and projection" have =
been
shared with other trees.
Expect a few minor conflicts with other trees (DRM, PM, PWM), and a minor
semantic one with the Rust tree [1].
Thanks,

Driver core changes for 7.3-rc1
- container_of:
- Apply typeof_member(), remove the local __mptr variable to eliminate
variable shadowing warnings on nested container_of() calls, and remove
unnecessary parentheses.
- core:
- Add driver name to probe debug print for initcall_debug.
- Avoid repeatedly printing the same 'Fixed dependency cycle' log.
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device().
- Remove statistics group if encryption group creation fails in
transport_add_class_device().
- debugfs:
- Fix lockdown check for mmap_prepare().
- Warn if file creation failed due to uninitialized debugfs.
- device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from DEV_PROP_REF
properties to enable automatic probe ordering. Add kunit-managed fwnode
helpers and test coverage.
- Fix infinite loop in fwnode_for_each_child_node() when the secondary fw=
node
has more than one child. Add test cases.
- Fix out-of-bounds access in software_node_get_reference_args() when cal=
led
with index -1 (UINT_MAX).
- Refactor to use RAII approach with __free().
- Add Bartosz Golaszewski as software node reviewer.
- firmware loader:
- Fix race where a sysfs fallback request can complete before being queue=
d as
pending, leading to a use-after-free on the next fallback request.
- Reject 0-size built-in firmware and fail the build on empty firmware fi=
les
in CONFIG_EXTRA_FIRMWARE.
- kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros and
allow the constification of kobject attributes, enabling them to reside=
in
read-only memory.
- platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(), an=
d
platform_device_set_of_node_from_dev() helpers that encapsulate firmwar=
e
node reference counting for dynamically allocated platform devices. Con=
vert
all in-tree users that manually assigned dev.of_node or dev.fwnode, fix=
ing a
pre-existing refcount bug in powermac. Switch to counting references o=
f all
firmware node types, not only OF nodes.
- Unify the release path for dynamically allocated platform devices by
removing platform_device_release_full(). Amend the fwnode setter API
contract to warn if a primary software node is overwritten. Add KUnit t=
ests
for correct software node removal on device unregistration.
- Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant ForLt ty=
pes.
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements from
kernel::transmute traits to zerocopy traits.
- Device:
- Add BoundInternal device context and InternalBoundContext trait for b=
us
abstractions that need internal access to a bound device.
- Make the lifetime on Core and CoreInternal invariant to prevent coerc=
ion
to shorter lifetimes.
- Devres:
- Fix race between concurrent revokers where the losing revoker could r=
eturn
before the winning revoker finished dropping the inner data, causing
use-after-free.
- Ensure revocation is complete before the device finishes unbinding by
making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens 'static=
back
to the caller's borrow scope. Implement ForLt and CovariantForLt for =
Bar,
IoMem, and ExclusiveIoMem.
- Driver:
- Switch from index-based to pointer-based device ID info lookup, stori=
ng
static references in driver_data. Centralize device ID handling in
device_id.rs, removing the open-coded ACPI/OF matching logic and dupl=
icate
ID table from driver.rs.
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type for the
existing untyped case), create view types representing subregions of =
a
mapped I/O region, and add io_project!() for safely creating subviews=
.
- Split Io into a base trait (IoBase) and an extension trait (Io) with =
a
blanket implementation, preventing implementers from overriding provi=
ded
methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile access, a=
nd
make Coherent implement Io via an I/O view type. Add IoSysMap as sum=
type
of Mmio and SysMem. Add copying methods (memcpy_{from,to}io()) and
read_val()/write_val() for typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!() for
primitives and copying methods for aggregates; drop the old macros.
Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro, remove
unused rule arguments, and use path fragments for alias destinations.
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers by
removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources.
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning type,
giving drivers explicit control over the allocation lifetime.
IrqVector embeds a resolved IrqRequest, making the conversion
infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX, PCI_IRQ_=
MSI,
or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline.
- Serdev:
- Add Rust abstractions for the serial device bus, including serdev::Dr=
iver
trait, serdev::Device wrapping struct serdev_device, and serdev::Adap=
ter
implementing RegistrationOps. Includes a sample driver. Markus Probs=
t
takes over as serdev maintainer for both C and Rust code.
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an unsaf=
e
CovariantForLt subtrait guaranteeing covariance, enabling invariant t=
ypes
(e.g. those containing Mutex<&'bound T>) to participate in the ForLt
abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef.
- misc:
- Avoid iattr allocation in kernfs listxattr by using kernfs_iattrs_noall=
oc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark internal prope=
rty
data as private for kernel-doc, and add property.h/fwnode.h to driver-a=
pi
infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h.
please pull the x86/cpu lineup for v7.3-rc1. This is conflicting with other work from tip, see end of mail for possible resolution. Thx. --- - Get rid of static_cpu_has() - one less API to care about testing CPU features - Unify the handling of CPU core types (performance, efficient, etc) by mapping the vendor-specific types to Linux ones - Continuation of the work of Ahmed Darwish to centralize CPUID leafs representation
This pull request contains two fixes for Alpha floating-point exception handling, two clang-related fixes, the preparatory changes from the generic-entry series, an interrupt-entry lockdep fix, two Marvel/EV7 IRQ fixes, an RTC fix, and one header cleanup. The generic-entry preparation adds regset-based ptrace and core dumps, ARCH_STACKWALK and lockdep hardirq-state tracking. These changes are useful independently and enable previously missing debugging facilities on Alpha. The final patch switching Alpha to GENERIC_ENTRY is intentionally not included in this pull request. I am deferring that change to allow further testing and to reduce the risk of conflicts with ongoing entry-path work elsewhere in the kernel. alpha updates for v7.3 - alpha: read $gp and $sp explicitly for clang - alpha: pass -Wa,-mev6 only when using GNU as - alpha: annotate hardirqs-off on IPL 7 interrupt entry - alpha: run the remote RTC access in a worker, not an IPI callback - alpha: don't leak hardware-fabricated FP exception bits to user space - alpha: fix ieee_swcr_to_fpcr setting FPCR_DNOD unconditionally - alpha: enable lockdep hardirq state tracking - alpha: use raw spinlocks for low-level platform locks - alpha: provide ftrace return address support for lockdep - alpha: make irqflags helpers operate on IPL state - alpha: add ARCH_STACKWALK-based stacktrace support - alpha: enable regset-based ptrace and core dumps - alpha: marvel: Fix lock ordering in init_io7_irqs() - alpha: marvel: Fix irq_set_status_flags to use correct IRQ number - alpha: remove unnecessary architecture-specific <asm/device.h>
please pull the x86/cache lineup for v7.3-rc1. Thx. --- - How refreshing: no new features but a whole pile of fixes to more or less serious issues reported by Sashiko along with miscellaneous cleanups all over the place. All except one by Reinette Chatre, the one by Tony Luck
There are two things in here of note. First, there are fixes to reduce the time that the TLB flushing code sits around with interrupts disabled. It should be well tested, but it's certainly something to keep an eye on. Second is a little back-and-forth in the interactions between the set_memory*() locking and DEBUG_PAGEALLOC. There was a slightly painful re-discovery of why DEBUG_PAGEALLOC has special locking rules, but the code did end up better for it. -- * Fix pkey_alloc() return value when pkeys are not supported * Allow preemption during IPI completion waiting to improve wakeup latency * Convert more x86 page table code to ptdescs * Fixes and cleanups for set_memory*() locking, mostly around large pages
exceptions whenever they do port I/O. The guest then does some instruction decoding and makes a call up to the host for help. That decoding had a couple of bugs. Fix those bugs. Use an existing and now shared KVM helper for one of them. -- * Fix TDX port I/O bugs
pretty benign, just adding some documentation and removing a super stale comment about an LED driver that was moved long ago. -- * Document the intricacies of GS context switching * Remove old TODO message about Geode LED driver
pointer unwinder when it encounters FRED stack frames. -- Fix frame pointer unwinder when it encounters FRED stack frames
Probes updates for v7.3:
- probes: Advanced BTF typecasting and variable fetch enhancements
. Typecast support across probe events: Extended BTF typecasting syntax
(e.g., (STRUCT)PARAM->MEMBER) to kprobes, uprobes, and fprobes on
function entry and return.
. Nested typecasts: Added support for chaining and nesting typecasts up
to 3 levels, including casting registers and stack variables.
. Field specifier option: Added (STRUCT,FIELD) syntax to emulate
container_of(), allowing retrieval of parent structures from member
pointers.
. $current variable support: Introduced $current special variable to
access the running task_struct via BTF dereferencing.
. Per-CPU variable access: Added this_cpu_read() and this_cpu_ptr()
fetcharg methods to trace CPU-local data safely.
. Fetcharg bytecode dumper: Added CONFIG_PROBE_EVENTS_DUMP_FETCHARG to
dump the compiled fetcharg bytecode instructions as comments in
dynamic_events.
. Extended symbol name handling: Removed the MAX_COMMON_HEAD_LEN limit
and extended MAX_ARGSTR_LEN to 256 bytes, enabling probing of long
symbols, mangled Rust symbols and complex BTF expressions.
. eprobe variable syntax: Allowed eprobes to reference event fields
directly without requiring a '$' prefix.
. Cleanup unused parameters, redundant codes, duplicate macros and
pointer arithmetic.
. Use a ternary operator for simplifying fetch_type_from_btf_type().
- bootconfig / boottime-trace: Expanded dynamic probe support
. Added boot-time tracing configuration support for event probes
(eprobes), function probes (fprobes), and tracepoint probes
(tprobes).
. ftrace2bootconfig: Allowed comment lines ('#') in dynamic_events file.
- fprobe / kprobe: Optimization, robustness, and cleanups
. fprobe: Simplified fprobe_remove_ips() by reusing graph and ftrace
helpers.
. fprobe: Removed __packed attribute from struct __fprobe_header to avoid
unaligned memory access penalties on RISC architectures.
. kprobe & fprobe: Removed redundant memset() calls in perf event probe
handlers.
. kprobes: Replaced legacy __ASSEMBLY__ with __ASSEMBLER__ in header
files.
- selftests & refactoring:
. Refactored parse_probe_arg() and parse_probe_vars(), and eliminated
recursion in probe argument parsing to protect kernel stack depth.
. Added selftests for BTF typecasts and module probing without module
prefixes.
. Forced LC_ALL=C in ftracetest to prevent test failures on localized
systems.
. Refactored btf_type_skip_modifiers() to remove ignored id parameter.
. Sorted ERRORS list in trace_probe.h alphabetically.
. Fixed typo in fprobe docs, and trace_fprobe function name.
. Renamed FETCH_OP_DATA to FETCH_OP_IMMSTR.
. Made file offset error message probe-agnostic.
probes-v7.3
This is the fixed version of the primary PR from the GPIO tree for this merge window. It's essentially the same except that it contains two additional merge commits: one pulling in the upstream v7.2 tag in order to address a conflict between my for-next and your master branches. The second pulls in an immutable branch from Mark Brown I missed before but which contains a commit on which some of the regmap changes depend. There's one new driver for the Realtek DHC RTD1625 GPIO controller. If adding it, reverting it and then adding it again raises your eyebrow: this was done becuase the initial implementation - while correct - didn't use the gpio-regmap abstraction that suited it nicely. The conversion was done after I had already merged v7.2-rc2 into my tree so instead of rebasing, I went with a revert for a cleaner git blame output. The merges you see - other than pulling in your upstream tags with conflicting fixes - are for a PR from Arnd containing his work on further isolating legacy GPIO APIs and the fw_devlink support for software nodes that will go upstream via the driver core tree. Nothing else really stands out, details are in the signed tag. Please consider pulling. Thanks, Bartosz gpio updates for v7.3-rc1 GPIO core: - extend the gpio-regmap abstraction layer with more features allowing users to override configuration setting, translate register values and masks and enable/disable interrupts - extend GPIO kunit tests with suites verifying probe ordering by software node devlink support and software node hogs - shrink GPIO kunit initialization code - coding style updates (remove commas from sentinels where applicable) - with all users now converted treewide to using real firmware node links for software node GPIO lookup: remove the deprecated label-matching mechanism from from GPIO core - drop redundant return value check of nonseekable_open() in gpiolib-cdev - use IRQ trigger helpers where applicable Driver updates: - refactor error paths and logging in gpio-nomadik - use more modern interfaces for getting resources in gpio-rockchip, gpio-bt8xx and gpio-pca9570 - add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610 - drop unused FILONOFF macro from gpio-rcar - extend build coverage of ioport GPIO drivers with COMPILE_TEST=y - only enable the gpio-rtd driver by default with ARCH_REALTEK=y to avoid bloating the build - refactor coding style in several drivers - use correct endianess translation in gpio-pcf85x - add wake-up interrupt support to gpio-mvebu - apply initial value in direction output setter in gpio-by-pinctrl Misc: - replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h which now exports all the deprecated APIs - select GPIOLIB_LEGACY in Kconfig where required treewide - use software nodes for gpio-keys in MFD drivers Devicetree bindings: - describe the realtek rtd1625 GPIO controller - document new models for gpio-pca95xx and gpio-cadence - document new property in gpio-rockchip

Konstantin

Nothing super unusual is cycle. I did manage to end up with two selftests pull requests, appropriately named selftests and selftests2 in the spirt of KVM uAPI, with a minor conflict between them. I originally created a dedicated topic branch for the new irq_test to isolate a dependency on the VFIO library, but then realized I really wanted to use some of the new infrastructure APIs in other tests. Assuming you merge selftests before selftests2, the resolution I've been using is to use the kvm_ prefixes pthread APIs (which assert success), but otherwise keep the functional changes from "selftests".
This update includes the following changes: API: - Add af_alg_restrict sysctl and white list. - Fix potential suspend/resume races in hwrng. Algorithms: - Optimize vli additive operations using compiler builtins in ecc. Drivers: - Remove unsafe/deprecated algorithms from qce. - Mark qce as BROKEN. - Add runtime PM and interconnect bandwidth scaling support to qce. - Remove crypto_rng from qcom, sun8i and caam. - Fix SG list issues in iaa. - Fix SEV init path bugs in ccp.
please pull a x86/alternatives cleanup for v7.3-rc1. Thx. --- - Remove the smp_locks alternatives machinery which was used to patch out lock prefixes when running a SMP kernel on a uniprocessor machine
please pull a single ras/core fixlet for v7.3-rc1. Thx. --- - Add mce=print_all to the mce= kernel cmdline params documentation
Various ext4 updates for 7.3-rc1, including:
* Improve performance by allowing parallel DIO writes when we were
previously being overly conservative when checking whether it was safe
to avoid requiring an exclusive lock
* Improve the performance of ext4_mb_prefetch() used by fallocate() by
avoiding work when it is not needed
* Remove the unnecessary custom end_io function ext4_end_buffer_io_sync()
* Improve performance when performing an overwrite to an already uptodate folio
* Clean up how we handle deallocating EA inodes to avoid a potential
lock ordering issue when there is a failed mount while an EA inode is
still being evicted.
* Use str_plural() instead of a custom macro
* Avoid soft lockups or RCU stalls if there are many busy buffers
(caused by heavy I/O) while checkpointing
* Use scoped NOFS when starting a handle in nojournal mode
* Align fields in handle structure to optimize setting and getting
the h_type and h_line_no fields
* Fix documentation of the meta_bg block group layout
* Bug fixes, including
- Fix a potential out-of-bounds read in ext4_read_inline_dir()
- Fix a potential deadlock when concurrent xattr operations are racing
with each other when some of the xattrs are using the ea_inode feature.
- Fix a spurious warning with data=journal that can be triggered when
writeback races with remounting the file system read-only
- Fix a potential deadlock when EXT4_IOC_MIGRATE races with a file system
freeze operation
- Make sure all in-flight direct I/O operations are complete before
falling back to buffered I/O.
- Handle IOCB_NOWAIT properly when performing a extending DAX write
- Prevent potentially sleeping on a block allocation when
IOCB_NOWAIT is set
- Fix potential races when racing an inline data write with a page fault
- Propagate errors when adding or removing extent ranges
during a fast commit replay
- Avoid trying to expand an inode's extra size when it is being
evicted to avoid a number of corner case or deadlocks
- Avoid spurious error when retrying inode extra size expansion
- Fix corner cases where we underestimate the number of journal
credits needed
- Avoid hangs/crashes/WARNINGS caused by maliciously corrupted
file systems
- Don't issue spurious orphan clean message on RO file systems
- Avoid leaving the file system in an inconsistent state after a
crash when a WRITE_ZEROS in progress converting an unwritten
extent to a written extent
- Handle WRITE_ZEROS correctly when there are some partially dirtied
regions in the page cache
- Pass errors during zero-rage, truncate, or punch hole to the caller
if ext4_get_block() fails
- Wait for writeback to finish when triggered by zero-range or
zero-range for those devices that require stable writes
- If the reserved gid superblock field is set, set the reserved gid
instead of the reserved uid
Could consider these commits for 7.3-rc1? The most notable enhancement is to allow passing source fds via fsconfig() for composefs. The others are all various fixes. All commits have been in -next and no potential merge conflict is observed. Thanks, Gao Xiang Changes since last update: - Allow source fds via fsconfig(), in addition to source paths - Use dedicated metadata inodes for file-backed mounts - Disallow invalid interlaced ztailpacking pclusters - Validate on-disk compression algorithm IDs against supported ones - Fix unused pcluster pools on higher page-size platforms
Thanks,
Guenter

Hi Stephen, Yixun Lan RISC-V SpacemiT clock changes for 7.3 - Add clock for UFS controller - Add new I2S clock and fixes
Hi Peter,
The major changes are the introduction of preempt_count backed interrupt
disabling level tracking, i.e. the local_interrupt_{enable, disable}(),
along with the user (the Rust SpinLockIrq). This should unblock a few
drivers in Rust. For other changes, please refer the following change
log.
Rust synchronization changes for v7.3:
* Safe SpinLockIrq
- Introduce refcounted interrupt disabling and corresponding spinlock
primitives, which tracks the interrupt disabling "level" in
preempt_count, as a result, this set of primitives can automatically
restore the interrupt disabling status when the outermost critical
section exits.
- Based on the above, a SpinLockIrq is introduced on the Rust side,
the guard of which will automatically restore the interrupt
disabling status when dropped. This avoid playing unsafe games when
using irq disabled spinlocks.
* Add synchronize_rcu() safe abstraction.
* Generic memory barrier: this extends our Rust barrier primitives to
include more barriers for DMA as well.
* Replace the atomic usage in Revocable with LKMM atomics.

Steve, rv changes for v7.3 (for-next) Summary of changes: - Switch LTL and DOT parsers to Lark in code generation tool The rvgen code generation tool originally parsed DOT files and LTL specifications using custom string parsing and Ply, which is no longer maintained. The DOT parser was fragile and prone to failure on minor format variations. Both LTL and DOT parsers have been rewritten to use the Lark parsing library. - Simplify Hybrid Automata clock variables The clock variables in hybrid automata monitors now use a single representation of the elapsed time since the clock was reset, rather than converting between invariant and guard representations. This allows simpler code generation for the newly refactored parser. - Generate cleanup hook for per-obj monitor The code generation scripts now adds a cleanup function to per-obj monitors for the user to wire to the appropriate event (e.g. sched_process_exit for tasks). - Reduce read_lock scope during per-task cleanup Take the tasklist_lock only when necessary, that is when iterating over for_each_process_thread(). - Simplify task monitor slot management Only rely on the slot array for per-task slot management to avoid inconsistency with the unused counter. - Improve rvgen code robustness and templates Use pathlib in rvgen and improve kernel path discovery. Also improve consistency across templates when generating code (e.g. author placeholder and monitor struct name). - Update rtapp sleep monitor Simplify the sleep monitor by excluding kernel threads and updating the nanosleep check to focus only on CLOCK_REALTIME. Also switch to use the sched_exit tracepoint to run in the context of the offending (wakee) task. - Add wakeup monitor Add the new rtapp/wakeup monitor to detect when lower-priority tasks wake up higher-priority ones, complementing the existing sleep monitor by running in the waker context and capturing its stack trace. - Fix tools/rv exit status on failure Ensure the rv tool returns a failure exit code when a monitor fails to start because it was already running. - Add automated selftests for tools/rv and rvgen Introduced automated bash selftests to validate rv monitor listing and execution under different configurations. Added tests for the rvgen code generator, validating generated files against expected output (golden). Tests are reachable via make check. - Add KUnit test coverage for verification monitors Added comprehensive KUnit tests to validate the functionality of deterministic, hybrid, and LTL monitors by emulating event sequences and timing in a mock environment without affecting the running kernel while expecting mock reactions to fire. Ensure real RV monitors cannot run during KUnit tests to avoid state corruption. - Mock current in rv monitors Mock the call to current in rv monitors when the KUnit tests are built to allow them to run the test on dummy tasks. No overhead is expected when KUnit tests aren't running. - Introduce rvgen kunit subcommand Added a new 'kunit' subcommand to rvgen to automatically patch an already generated monitor with KUnit integration templates by parsing its event handlers and creating the required mock structures and initializations. - Refine kernel verification selftests Added new selftests for the deadline and stall monitors and rearranged the existing wwnr_printk test to resolve flakiness. Additionally, fixed an issue in the selftests framework where negative assertion failures were not correctly propagated due to shell rules.
SoCFPGA firmware updates for v7.3 - Document stratix10-rsu for QSPI size and erase size - Add method to retrieve device info table using RSU - Add support for hardware monitoring using service driver
Hi Stephen and Michael,
Here's some changes that were posted since June 29th that I feel are ready to
be picked up. These are changes where a clk submaintainer typically won't send
the changes in via a separate pull.
Note that I have a separate outstanding pull for some changes posted during
the last merge window that I feel is also ready for inclusion.
https://lore.kernel.org/linux-clk/[email protected]/
There is a minor conflict in drivers/clk/clk-si544.c between these two pulls.
You'll need to add the .name and .driver_data name initializers like the
following based on the work from Uwe Kleine-K�nig:
- { "si544a", (kernel_ulong_t)&clk_si544a_info },
+ { .name = "si544a", .driver_data = (kernel_ulong_t)&clk_si544a_info },
With the conflict resolved, I verified that both merges can go in together, or
individually.
clk: Clock driver updates for v7.3 (round two)
- New clock controller drivers for the Cix Sky1 audio subsystem (AUDSS),
UltraRISC DP1000, and MediaTek MT8173 MFG_TOP, along with their devicetree
bindings. Si549 support was added to the existing si544 driver.
- New clock and reset support for the Aspeed AST2700 PECI controller and Airoha
EN7523 PCIe PERSTOUT reset lines.
- The clk core gains devm_clk_bulk_get_enable() as the mandatory counterpart to
the existing optional variant, and exports
devm_clk_hw_register_composite_pdata() for modular drivers.
- Tegra gets a proper EMC clock implementation for Tegra114, 48MHz pll_p_out1
support needed for UEFI on Surface2, and the Xilinx clocking-wizard gains PLL
charge pump/lock parameter programming during dynamic reconfiguration.
- Bug fixes for a NULL pointer dereference from uninitialized clk_init_data in
the eswin driver, an IO remap leak in the MediaTek pllfh error path, inverted
gate control for MT8135 devapc_ck, a missing OF node put in tegra124-emc on
registration failure, a prepare reference leak in the palmas driver,
unregistered PLLs on MT6735 probe failure, a missing kasprintf NULL check in
pmc_atom, PCIe warm boot instability in the Airoha EN7523 driver, and a
clocking-wizard clock difference detection bug.
- Various cleanups across tegra, st, and mvebu providers to stop misusing the
consumer clock API, along with other minor fixes and improvements.

Hi Stephen, Here is a pull for the clk-eyeq driver adding support for Mobileye EyeQ7H SoC. This pull request is a clean rebase of the version that was posted during the last release cycle[1] and it was also posted as a patch series[2= ]. Alongside the changes to the clk-eyeq driver, this pull request also provides the dt-bindings reviewed by Krzysztof Kozlowski, a change to the reset-eyeq driver acked by Philipp Zabel and a small rework of the fixed-factor clocks reviewed by Brian Masney.

T-HEAD clock changes for v7.3 There is just one change for this cycle. It allows COMPILE_TEST to select the th1520 clk driver without having CONFIG_ARCH_THEAD enabled.
Hi, I created my riscv-confg branches to shepard defconfig patches related to the riscv platforms that I maintain. The branches are in linux-next. For 7.3, there is just a single patch for the WiFi driver on the TH1520-based LPi4a. Thanks, Drew RISC-V defconfig changes for 7.3 Enable PCA953X GPIO driver to properly probe Wifi pwrseq driver on the Sipeed Lichee Pi 4a board which is based on the T-HEAD TH1520 SoC.

ARM: platform and feature deprecation for 7.3 This is attempt to bring the source code to the state that we discussed back in 2024, regarding a timeline for deprecating and removing features, in particular platforms and ABIs that are basically unused and are also getting in the way of maintenance. The earlier consensus was to remove these features in 2025 or 2026 after the corresponding LTS kernel release. I would suggest pushing these to early 2027 now, see the patch description for details on each one: - all board files that are still not converted to DT (except for OMAP1 and S3C) - iWMMXt FPU support - ARMv6/ARM1136r0 (not ARMv6K/ARM1136r1/ARM1176) along with the OMAP24xx and i.MX31 SoCs using it - Cortex-M3/M4/M7 based microcontroller support (stm32, imxrt, lpc18xx, samv7) - LSI Axxia platform - OABI, OABI-compat and NWFPE are confined to StrongARM based builds and scheduled for removal once StrongARM is gone. - DEPRECATED_PARAM_STRUCT, which was originally scheduled for removal in 2006 (!) The ARCH_S3C64XX platform was scheduled for removal in 2024, but is still actively used and will get removed once Mark Brown stops using it. The OMAP1 platform has some remaining boardfiles and is expected to get converted to DT. Big-endian ARMv7 CPU support is not scheduled for removal but marked as broken the same way as ARM64 has, to reduce the need for testing unused configurations. This may be removed in the future if arm64 does it as well. Note that big-endian ARMv5 support is can still be enabled since the patches to revive little-endianm mode are still fresh. Regarding actually removing the code, I would suggest linux-7.4 (January 2027), removing both the board files and any drivers that have either become newly unused or were missed in a previous machine removal series, followed by removing support for then unused CPUs a release later.

Hey folks, with for the 7.2 merge window. Some of these patches date from 2024, so I have elected not to squash or have the submitters of the clock changes etc resubmit the original k230 series with their stuff squashed in so that the history of the initial bring-up is retained, particularly given Yangyu's detailed commit message in "riscv: dts: add initial canmv-k230 and k230-evb dts" that covers the testing done and decisions made about supporting the standard Svpbmt extension or T-Head custom MAEE stuff etc. Thanks, Conor. RISC-V devicetrees for v7.3 - early k230 material Canaan: Support for the k230 SoC that was too late for the 7.2 window. Consists of some bindings not taken by the various subsystem maintainers, the original dts patches from Yangyu back in 2024 and the more recent clock, reset and pinctrl additions from various contributors.

If it's possible to get this into to kvm/next before you disappear on holiday,
please pull a set of selftest changes that (lightly) touch all x86 tests that
use nested virtualization in any way.
If it's too late to get this into kvm/next, I'd say just ignore this pull
request and I'll include them in the normal 7.3 selftests pull requests. I
don't think there will be any cross-branch conflicts to juggle? But I've had
these sitting in -next for a few weeks now, and getting them into kvm/next
"now" would all but guarantee I won't end up having to play weird games with
selftests patches.
Thanks!
KVM selftests for 7.3, early edition
- Automatically allocate a full page for L2 guest stacks on x86 instead of
requiring test-specific L1 guest code to carve out a portion of the L1
stack for L2 usage, and to ensure the L2 stack also adheres to the x86-64
calling convention ABI.
- Add a selftest to verify {Guest,Host}-Only behavior in x86's mediated PMU.
