Pull xfs updates from Dave Chinner:
"There are relatively few updates this cycle; half the cycle was eaten
by a grue, the other half was eaten by a tricky data corruption issue
that I still haven't entirely solved.
Hence there's no major changes in this cycle and it's largely just
minor cleanups and small bug fixes:
- fixes for filesystem shutdown procedure during a DAX memory failure
notification
- bug fixes
- logic cleanups
- log message cleanups
- updates to use vfs{g,u}id_t helpers where appropriate"

Pull f2fs updates from Jaegeuk Kim:
"This round looks fairly small comparing to the previous updates and
includes mostly minor bug fixes. Nevertheless, as we've still
interested in improving the stability, Chao added some debugging
methods to diagnoze subtle runtime inconsistency problem.
Enhancements:
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fixes:
- DIO write fix for zoned devices
- do out-of-place writes for cold files

Pull 9p updates from Dominique Martinet:
"Smaller buffers for small messages and fixes.
The highlight of this is Christian's patch to allocate smaller buffers
for most metadata requests: 9p with a big msize would try to allocate
large buffers when just 4 or 8k would be more than enough; this brings
in nice performance improvements.
There's also a few fixes for problems reported by syzkaller (thanks to
Schspa Shi, Tetsuo Handa for tests and feedback/patches) as well as
some minor cleanup"

Pull gfs2 updates from Andreas Gruenbacher:
- Make sure to initialize the filesystem work queues before registering
the filesystem; this prevents them from being used uninitialized.
- On filesystem withdraw: prevent a a double iput() and immediately
reject pending locking requests that can no longer succeed.
- Use TRY lock in gfs2_inode_lookup() to prevent a rare glock hang
during evict.
- During filesystem mount, explicitly make sure that the sb_bsize and
sb_bsize_shift super block fields are consistent with each other.
This prevents messy error messages during fuzz testing.
- Switch from strlcpy to strscpy.

Pull MM updates from Andrew Morton:
- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any
negative reports (or any positive ones, come to that).
- Also the Maple Tree from Liam Howlett. An overlapping range-based
tree for vmas. It it apparently slightly more efficient in its own
right, but is mainly targeted at enabling work to reduce mmap_lock
contention.
Liam has identified a number of other tree users in the kernel which
could be beneficially onverted to mapletrees.
Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
at [1]. This has yet to be addressed due to Liam's unfortunately
timed vacation. He is now back and we'll get this fixed up.
- Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
clang-generated instrumentation to detect used-unintialized bugs down
to the single bit level.
KMSAN keeps finding bugs. New ones, as well as the legacy ones.
- Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
memory into THPs.
- Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
support file/shmem-backed pages.
- userfaultfd updates from Axel Rasmussen
- zsmalloc cleanups from Alexey Romanov
- cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
memory-failure
- Huang Ying adds enhancements to NUMA balancing memory tiering mode's
page promotion, with a new way of detecting hot pages.
- memcg updates from Shakeel Butt: charging optimizations and reduced
memory consumption.

Pull x86 mm updates from Dave Hansen:
"There are some small things here, plus one big one.
The big one detected and refused to create W+X kernel mappings. This
caused a bit of trouble and it is entirely disabled on 32-bit due to
known unfixable EFI issues. It also oopsed on some systemd eBPF use,
which kept some users from booting.
The eBPF issue is fixed, but those troubles were caught relatively
recently which made me nervous that there are more lurking. The final
commit in here retains the warnings, but doesn't actually refuse to
create W+X mappings.
Summary:
- Detect insecure W+X mappings and warn about them, including a few
bug fixes and relaxing the enforcement
- Do a long-overdue defconfig update and enabling W+X boot-time
detection
- Cleanup _PAGE_PSE handling (follow-up on an earlier bug)
- Rename a change_page_attr function"

Pull bitmap updates from Yury Norov:
- Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES (Phil Auld)
- cleanup nr_cpu_ids vs nr_cpumask_bits mess (me)
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
- optimize find_bit() functions (me)
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT()
macros.
- add find_nth_bit() (me)
Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)
if (n-- == 0)
return bit;
Also adds bitmap_weight_and() to let people replace this pattern:
tmp = bitmap_alloc(nbits);
bitmap_and(tmp, map1, map2, nbits);
weight = bitmap_weight(tmp, nbits);
bitmap_free(tmp);
with a single bitmap_weight_and() call.
- repair cpumask_check() (me)
After switching cpumask to use nr_cpu_ids, cpumask_check() started
generating many false-positive warnings. This series fixes it.
- Add for_each_cpu_andnot() and for_each_cpu_andnot() (Valentin
Schneider)
Extends the API with one more function and applies it in sched/core.

Pull tracing updates from Steven Rostedt:
"Major changes:
- Changed location of tracing repo from personal git repo to:
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git
- Added Masami Hiramatsu as co-maintainer
- Updated MAINTAINERS file to separate out FTRACE as it is more than
just TRACING.
Minor changes:
- Added Mark Rutland as FTRACE reviewer
- Updated user_events to make it on its way to remove the BROKEN tag.
The changes should now be acceptable but will run it through a
cycle and hopefully we can remove the BROKEN tag next release.
- Added filtering to eprobes
- Added a delta time to the benchmark trace event
- Have the histogram and filter callbacks called via a switch
statement instead of indirect functions. This speeds it up to avoid
retpolines.
- Add a way to wake up ring buffer waiters waiting for the ring
buffer to fill up to its watermark.
- New ioctl() on the trace_pipe_raw file to wake up ring buffer
waiters.
- Wake up waiters when the ring buffer is disabled. A reader may
block when the ring buffer is disabled, but if it was blocked when
the ring buffer is disabled it should then wake up.
Fixes:
- Allow splice to read partially read ring buffer pages. This fixes
splice never moving forward.
- Fix inverted compare that made the "shortest" ring buffer wait
queue actually the longest.
- Fix a race in the ring buffer between resetting a page when a
writer goes to another page, and the reader.
- Fix ftrace accounting bug when function hooks are added at boot up
before the weak functions are set to "disabled".
- Fix bug that freed a user allocated snapshot buffer when enabling a
tracer.
- Fix possible recursive locks in osnoise tracer
- Fix recursive locking direct functions
- Other minor clean ups and fixes"

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
- Huawei reported that when they updated their kernel from 4.4 to
something much newer, some userspace code they had broke, the culprit
being the accidental removal of O_NONBLOCK from /dev/random way back
in 5.6. It's been gone for over 2 years now and this is the first
we've heard of it, but userspace breakage is userspace breakage, so
O_NONBLOCK is now back.
- Use randomness from hardware RNGs much more often during early boot,
at the same interval that crng reseeds are done, from Dominik.
- A semantic change in hardware RNG throttling, so that the hwrng
framework can properly feed random.c with randomness from hardware
RNGs that aren't specifically marked as creditable.
A related patch coming to you via Herbert's hwrng tree depends on
this one, not to compile, but just to function properly, so you may
want to merge this PULL before that one.
- A fix to clamp credited bits from the interrupts pool to the size of
the pool sample. This is mainly just a theoretical fix, as it'd be
pretty hard to exceed it in practice.
- Oracle reported that InfiniBand TCP latency regressed by around
10-15% after a change a few cycles ago made at the request of the RT
folks, in which we hoisted a somewhat rare operation (1 in 1024
times) out of the hard IRQ handler and into a workqueue, a pretty
common and boring pattern.
It turns out, though, that scheduling a worker from there has
overhead of its own, whereas scheduling a timer on that same CPU for
the next jiffy amortizes better and doesn't incur the same overhead.
I also eliminated a cache miss by moving the work_struct (and
subsequently, the timer_list) to below a critical cache line, so that
the more critical members that are accessed on every hard IRQ aren't
split between two cache lines.
- The boot-time initialization of the RNG has been split into two
approximate phases: what we can accomplish before timekeeping is
possible and what we can accomplish after.
This winds up being useful so that we can use RDRAND to seed the RNG
before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in
addition to other early uses of randomness. The effect is that
systems with RDRAND (or a bootloader seed) will never see any
warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And
kfence benefits from getting a better seed of its own.
- Small systems without much entropy sometimes wind up putting some
truncated serial number read from flash into hostname, so contribute
utsname changes to the RNG, without crediting.
- Add smaller batches to serve requests for smaller integers, and make
use of them when people ask for random numbers bounded by a given
compile-time constant. This has positive effects all over the tree,
most notably in networking and kfence.
- The original jitter algorithm intended (I believe) to schedule the
timer for the next jiffy, not the next-next jiffy, yet it used
mod_timer(jiffies + 1), which will fire on the next-next jiffy,
instead of what I believe was intended, mod_timer(jiffies), which
will fire on the next jiffy. So fix that.
- Fix a comment typo, from William.

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab fixes from Vlastimil Babka:
- The "common kmalloc v4" series [1] by Hyeonggon Yoo.
While the plan after LPC is to try again if it's possible to get rid
of SLOB and SLAB (and if any critical aspect of those is not possible
to achieve with SLUB today, modify it accordingly), it will take a
while even in case there are no objections.
Meanwhile this is a nice cleanup and some parts (e.g. to the
tracepoints) will be useful even if we end up with a single slab
implementation in the future:
- Improves the mm/slab_common.c wrappers to allow deleting
duplicated code between SLAB and SLUB.
- Large kmalloc() allocations in SLAB are passed to page allocator
like in SLUB, reducing number of kmalloc caches.
- Removes the {kmem_cache_alloc,kmalloc}_node variants of
tracepoints, node id parameter added to non-_node variants.
- Addition of kmalloc_size_roundup()
The first two patches from a series by Kees Cook [2] that introduce
kmalloc_size_roundup(). This will allow merging of per-subsystem
patches using the new function and ultimately stop (ab)using ksize()
in a way that causes ongoing trouble for debugging functionality and
static checkers.
- Wasted kmalloc() memory tracking in debugfs alloc_traces
A patch from Feng Tang that enhances the existing debugfs
alloc_traces file for kmalloc caches with information about how much
space is wasted by allocations that needs less space than the
particular kmalloc cache provides.
- My series [3] to fix validation races for caches with enabled
debugging:
- By decoupling the debug cache operation more from non-debug
fastpaths, extra locking simplifications were possible and thus
done afterwards.
- Additional cleanup of PREEMPT_RT specific code on top, by Thomas
Gleixner.
- A late fix for slab page leaks caused by the series, by Feng
Tang.
- Smaller fixes and cleanups:
- Unneeded variable removals, by ye xingchen
- A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu

Pull preempt RT updates from Thomas Gleixner:
"Introduce preempt_[dis|enable_nested() and use it to clean up various
places which have open coded PREEMPT_RT conditionals.
On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither
disabling preemption nor interrupts. Though there are a few places
which depend on the implicit preemption/interrupt disable of those
locks, e.g. seqcount write sections, per CPU statistics updates etc.
PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to
disable/enable preemption in the related code parts all over the
place. That's hard to read and does not really explain why this is
necessary.
Linus suggested to use helper functions (preempt_disable_nested() and
preempt_enable_nested()) and use those in the affected places. On !RT
enabled kernels these functions are NOPs, but contain a lockdep assert
to validate that preemption is actually disabled to catch call sites
which do not have preemption disabled.

Pull locking updates from Ingo Molnar:
- Disable preemption in rwsem_write_trylock()'s attempt to take the
rwsem, to avoid RT tasks hogging the CPU, which managed to preempt
this function after the owner has been cleared but before a new owner
is set. Also add debug checks to enforce this.
- Add __lockfunc to more slow path functions and add __sched to
semaphore functions.
- Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_*
toggles are disabled, to reduce LTO text size.
- Print more debug information when lockdep gets confused in
look_up_lock_class().
- Improve header file abuse checks.
- Misc cleanups

Merge additional generic power domains handling update and an
improvement of the PM callback definition macros for 6.1-rc1:
- Add an error message to be printed when a power domain marked as
"always on" is not actually on during initialization (Johan Hovold).
- Extend macros used for defining power management callbacks to allow
conditional exporting of noirq and late/early suspend/resume PM
callbacks (Paul Cercueil).

kernel threads running when an asynchronous error is detected (Shuai
Xue).
- Add ACPI support for handling system wakeups via GPIO wake capable
IRQs in addition to GPEs (Raul E Rangel).
- Make the system reboot code put ACPI-enabled systems into the S5
(system off) state which is necessary for some platforms to work as
expected (Kai-Heng Feng).

Pull ucounts update from Eric Biederman:
"Split rlimit and ucount values and max values
After the ucount rlimit code was merged a bunch of small but
siginificant bugs were found and fixed. At the time it was realized
that part of the problem was that while the ucount rlimits were very
similar to the oridinary ucounts (in being nested counts with limits)
the semantics were slightly different and the code would be less error
prone if there was less sharing.
This is the long awaited cleanup that should hopefully keep things
more comprehensible and less error prone for whoever needs to touch
that code next"

Pull ptrace update from Eric Biederman:
"ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Recently I had a conversation where it was pointed out to me that
SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
difficult for a tracer to handle.
Keeping SIGKILL working after the process has been killed is pain from
an implementation point of view.
So since the debuggers don't want this behavior let's see if we can
remove this wart for the userspace API
If a regression is detected it should only need to be the last change
that is the reverted. The other two are just general cleanups that
make the last patch simpler"
