file: ensure cleanup
Brown paper bag time. This is a silly oversight where I missed to drop
the error condition checking to ensure we clean up on early error
returns. I have an internal unit testset coming up for this which will
catch all such issues going forward.

Highlights include:
Bugfixes:
- Fix 'nlink' attribute update races when unlinking a file.
- Add missing initialisers for the directory verifier in various places.
- Don't regress the NFSv4 open state due to misordered racing replies.
- Ensure the NFSv4.x callback server uses the correct transport
connection.
- Fix potential use-after-free races when shutting down the NFSv4.x
callback server.
- Fix a pNFS layout commit crash.
- Assorted fixes to ensure correct propagation of mount options when the
client crosses a filesystem boundary and triggers the VFS automount
code.
- More localio fixes.
Features and cleanups:
- Add initial support for basic directory delegations.
- SunRPC back channel code cleanups.

lockref: add a __cond_lock annotation for lockref_put_or_lock
Add a cond_lock annotation for lockref_put_or_lock to make sparse happy with using it. Note that for this the return value has to be double-inverted as the return value convention of lockref_put_or_lock is inverted compared to _trylock conventions expected by __cond_lock, as lockref_put_or_lock returns true when it did not need to take the lock.

mm/huge_memory: replace can_split_folio() with direct refcount calculation
can_split_folio() is just a refcount comparison, making sure only the split caller holds an extra pin. Open code it with folio_expected_ref_count() != folio_ref_count() - 1. For the extra_pins used by folio_ref_freeze(), add folio_cache_ref_count() to calculate it. Also replace folio_expected_ref_count() with folio_cache_ref_count() used by folio_ref_unfreeze(), since they are returning the same values when a folio is frozen and folio_cache_ref_count() does not have unnecessary folio_mapcount() in its implementation.

mm/huge_memory: change folio_split_supported() to folio_check_splittable()
Patch series "Improve folio split related functions", v4. This patchset improves several folio split related functions to avoid future misuse. The changes are: 1. Consolidated folio splittable checks by moving truncated folio check, huge zero folio check, and writeback folio check into folio_split_supported(). Changed the function return type. Renamed it to folio_check_splittable() for clarification. 2. Replaced can_split_folio() with open coded folio_expected_ref_count() and folio_ref_count() and introduced folio_cache_ref_count(). 3. Changed min_order_for_split() to always return an order. 4. Fixed folio split stats counting. Motivation ========== This is based on Wei's observation[1] and solves several potential issues: 1. Dereferencing NULL folio->mapping in try_folio_split_to_order() if it is called on truncated folios. 2. Not handling of negative return value of min_order_for_split() in mm/memory-failure.c There is no bug in the current code. This patch (of 4): folio_split_supported() used in try_folio_split_to_order() requires folio->mapping to be non NULL, but current try_folio_split_to_order() does not check it. There is no issue in the current code, since try_folio_split_to_order() is only used in truncate_inode_partial_folio(), where folio->mapping is not NULL. To prevent future misuse, move folio->mapping NULL check (i.e., folio is truncated) into folio_split_supported(). Since folio->mapping NULL check returns -EBUSY and folio_split_supported() == false means -EINVAL, change folio_split_supported() return type from bool to int and return error numbers accordingly. Rename folio_split_supported() to folio_check_splittable() to match the return type change. While at it, move is_huge_zero_folio() check and folio_test_writeback() check into folio_check_splittable() and add kernel-doc. Remove all warnings inside folio_check_splittable() and give warnings in __folio_split() instead, so that bool warns parameter can be removed.

mm/sparse: fix sparse_vmemmap_init_nid_early definition without CONFIG_SPARSEMEM
When CONFIG_SPARSEMEM is disabled, the macro
sparse_vmemmap_init_nid_early(_nid, _use) passes two arguments, while the
actual function accepts only nid. Drop the extra argument _use.

f2fs-for-6.19-rc1
This series focuses on minor clean-ups and performance optimizations across sysfs, documentation, debugfs, tracepoints, slab allocation, and GC. Furthermore, it resolves several corner-case bugs caught by xfstests, as well as issues related to 16KB page support and f2fs_enable_checkpoint.

compiler_types.h: add "auto" as a macro for "__auto_type"
"auto" was defined as a keyword back in the K&R days, but as a storage type specifier. No one ever used it, since it was and is the default storage type for local variables. C++11 recycled the keyword to allow a type to be declared based on the type of an initializer. This was finally adopted into standard C in C23. gcc and clang provide the "__auto_type" alias keyword as an extension for pre-C23, however, there is no reason to pollute the bulk of the source base with this temporary keyword; instead define "auto" as a macro unless the compiler is running in C23+ mode. This macro is added in <linux/compiler_types.h> because that header is included in some of the tools headers, wheres <linux/compiler.h> is not as it has a bunch of very kernel-specific things in it.

Pin control changes for the v6.19 kernel cycle:
Core changes:
- Handle per-direction skew control in the generic pin config.
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message
if someone really want it.
New drivers:
- Samsung Exynos 8890 SoC support.
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out
"Axis Real-Time Picture Encoding Chip" and is tailored for camera
image streams and is something they have evolved for a quarter of
a century.
- Mediatek MT6878 SoC support.
- Qualcomm Glymur PMIC support (mostly just compatible strings).
- Qualcomm Kaanapali SoC TLMM support.
- Microchip pic64gx "gpio2" SoC support.
- Microchip Polarfire "iomux0" SoC support.
- CIX Semiconductors SKY1 SoC support.
- Rockchip RK3506 SoC support.
- Airhoa AN7583 chip support.
Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings.
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to schema.

This pull request is entirely SoC clk drivers, not for lack of trying to modify
the core clk framework. The majority diff wise is for the new Rockchip and Qualcomm clk drivers which is mostly lines and lines of data structures to describe the clk hardware in these SoCs. Beyond those two, Renesas continues to incrementally add clks to their SoC drivers, causing them to show up higher in the diffstat this time because they added quite a few clks all over the place.

mm/slab: introduce kvfree_rcu_barrier_on_cache() for cache destruction
Currently, kvfree_rcu_barrier() flushes RCU sheaves across all slab
caches when a cache is destroyed. This is unnecessary; only the RCU
sheaves belonging to the cache being destroyed need to be flushed.
As suggested by Vlastimil Babka, introduce a weaker form of
kvfree_rcu_barrier() that operates on a specific slab cache.
Factor out flush_rcu_sheaves_on_cache() from flush_all_rcu_sheaves() and
call it from flush_all_rcu_sheaves() and kvfree_rcu_barrier_on_cache().
Call kvfree_rcu_barrier_on_cache() instead of kvfree_rcu_barrier() on
cache destruction.
The performance benefit is evaluated on a 12 core 24 threads AMD Ryzen
5900X machine (1 socket), by loading slub_kunit module.
Before:
Total calls: 19
Average latency (us): 18127
Total time (us): 344414
After:
Total calls: 19
Average latency (us): 10066
Total time (us): 191264
Two performance regression have been reported:
- stress module loader test's runtime increases by 50-60% (Daniel)
- internal graphics test's runtime on Tegra234 increases by 35% (Jon)
They are fixed by this change.

genirq: Change hwirq parameter to irq_hw_number_t
The irqdomain implementation internally represents hardware IRQs as irq_hw_number_t, which is defined as unsigned long int. When providing an irq_hw_number_t to the generic_handle_domain() functions that expect and unsigned int hwirq, this can lead to a loss of information. Change the hwirq parameter to irq_hw_number_t to support the full range of hwirqs.

Significant patch series in this pull request:
- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric
Dumazet makes TCP a little faster.
- The 9 patch series "liveupdate: Rework KHO for in-kernel users" from

Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

tracing fixes for v6.19:
- Fix accounting of stop_count in file release On opening the trace file, if "pause-on-trace" option is set, it will increment the stop_count. On file release, it checks if stop_count is set, and if so it decrements it. Since this code was originally written, the stop_count can be incremented by other use cases. This makes just checking the stop_count not enough to know if it should be decremented. Add a new iterator flag called "PAUSE" and have it set if the open disables tracing and only decrement the stop_count if that flag is set on close. - Remove length field in trace_seq_printf() of print_synth_event() When printing the synthetic event that has a static length array field, the vsprintf() of the trace_seq_printf() triggered a "(efault)" in the output. That's because the print_fmt replaced the "%.*s" with "%s" causing the arguments to be off. - Fix a bunch of typos -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaTRsYBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrYpAQC3Qc5QMOlPjqGHXls/4IR4SBEAvsUi VZx3PdknfYCe3AD9HoYGOtrDDhSJ1tQbsWP5ud2jatHwL0zGAl3legNp7ww= =jlNP -----END PGP SIGNATURE----- Merge tag 'trace-v6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix accounting of stop_count in file release On opening the trace file, if "pause-on-trace" option is set, it will increment the stop_count.

Two fixes related to recent introduction of scoped_seqlock_read():
- Fix compiler build failures when a particular .config and
compiler build options variant doesn't result in the
expected removal of unused, catch-bugs portions of
scoped_seqlock_read() by the inliner at build time,
and cause a linker fail even in correct code.
- Match read-locking order in do_task_stat() and
do_io_accounting(). The inconsistency here was harmless
but unnecessary.

NFSD 6.19 Release Notes
Mike Snitzer's mechanism for disabling I/O caching introduced in
v6.18 is extended to include using direct I/O. The goal is to
further reduce the memory footprint consumed by NFS clients
accessing large data sets via NFSD.
The NFSD community adopted a maintainer entry profile during this
cycle. See
Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst
Work continues on hardening NFSD's implementation of the pNFS block
layout type. This type enables pNFS clients to directly access the
underlying block devices that contain an exported file system,
reducing server overhead and increasing data throughput.
The remaining patches in this pull request are clean-ups and minor
optimizations. Many thanks to the contributors, reviewers, testers,
and bug reporters who participated during the v6.19 NFSD development
cycle.
