Pull io_uring updates from Jens Axboe:
"Highlights from this cycles are things like request recycling and
task_work optimizations, which net us anywhere from 10-20% of speedups
on workloads that mostly are inline.
This work was originally done to put io_uring under memcg, which adds
considerable overhead. But it's a really nice win as well. Also worth
highlighting is the LOOKUP_CACHED work in the VFS, and using it in
io_uring. Greatly speeds up the fast path for file opens.
Summary:
- Put io_uring under memcg protection. We accounted just the rings
themselves under rlimit memlock before, now we account everything.
- Request cache recycling, persistent across invocations (Pavel, me)
- First part of a cleanup/improvement to buffer registration (Bijan)
- SQPOLL fixes (Hao)
- File registration NULL pointer fixup (Dan)
- LOOKUP_CACHED support for io_uring
- Disable /proc/thread-self/ for io_uring, like we do for /proc/self
- Add Pavel to the io_uring MAINTAINERS entry
- Tons of code cleanups and optimizations (Pavel)
- Support for skip entries in file registration (Noah)"

Pull xfs updates from Darrick Wong:
"There's a lot going on this time, which seems about right for this
drama-filled year.
Community developers added some code to speed up freezing when
read-only workloads are still running, refactored the logging code,
added checks to prevent file extent counter overflow, reduced iolock
cycling to speed up fsync and gc scans, and started the slow march
towards supporting filesystem shrinking.
There's a huge refactoring of the internal speculative preallocation
garbage collection code which fixes a bunch of bugs, makes the gc
scheduling per-AG and hence multithreaded, and standardizes the retry
logic when we try to reserve space or quota, can't, and want to
trigger a gc scan. We also enable multithreaded quotacheck to reduce
mount times further. This is also preparation for background file gc,
which may or may not land for 5.13.
We also fixed some deadlocks in the rename code, fixed a quota
accounting leak when FSSETXATTR fails, restored the behavior that
write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
where sgid directory inheritance wasn't quite working properly, and
fixed a bug where symlinks weren't working properly in ecryptfs. We
also now advertise the inode btree counters feature that was
introduced two cycles ago.
Summary:
- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when
adding to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing
during the freeze.
- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
- Disentangle log cleaning from log covering. This refactoring sets
us up for future changes to the log, though for now it simply means
that we can use covering for freezes, and cleaning becomes
something we only do at unmount.
- Speed up file fsyncs by reducing iolock cycling.
- Fix delalloc blocks leaking when changing the project id fails
because of input validation errors in FSSETXATTR.
- Fix oversized quota reservation when converting unwritten extents
during a DAX write.
- Create a transaction allocation helper function to standardize the
idiom of allocating a transaction, reserving blocks, locking
inodes, and reserving quota. Replace all the open-coded logic for
file creation, file ownership changes, and file modifications to
use them.
- Actually shut down the fs if the incore quota reservations get
corrupted.
- Fix background block garbage collection scans to not block and to
actually clean out CoW staging extents properly.
- Run block gc scans when we run low on project quota.
- Use the standardized transaction allocation helpers to make it so
that ENOSPC and EDQUOT errors during reservation will back out,
invoke the block gc scanner, and try again. This is preparation for
introducing background inode garbage collection in the next cycle.
- Combine speculative post-EOF block garbage collection with
speculative copy on write block garbage collection.
- Enable multithreaded quotacheck.
- Allow sysadmins to tweak the CPU affinities and maximum concurrency
levels of quotacheck and background blockgc worker pools.
- Expose the inode btree counter feature in the fs geometry ioctl.
- Cleanups of the growfs code in preparation for starting work on
filesystem shrinking.
- Fix all the bloody gcc warnings that the maintainer knows about. :P
- Fix a RST syntax error.
- Don't trigger bmbt corruption assertions after the fs shuts down.
- Restore behavior of forcing SIGBUS on a shut down filesystem when
someone triggers a mmap write fault (or really, any buffered
write)"

Pull iomap updates from Darrick Wong:
"The big change in this cycle is some new code to make it possible for
XFS to try unaligned directio overwrites without taking locks. If the
block is fully written and within EOF (i.e. doesn't require any
further fs intervention) then we can let the unlocked write proceed.
If not, we fall back to synchronizing direct writes.
Summary:
- Adjust the final parameter of iomap_dio_rw.
- Add a new flag to request that iomap directio writes return EAGAIN
if the write is not a pure overwrite within EOF; this will be used
to reduce lock contention with unaligned direct writes on XFS.
- Amend XFS' directio code to eliminate exclusive locking for
unaligned direct writes if the circumstances permit"

Pull erofs updates from Gao Xiang:
"This contains a somewhat important but rarely reproduced fix reported
month ago for platforms which have weak memory model (e.g. arm64).
The root cause is that test_bit/set_bit atomic operations are actually
implemented in relaxed forms, and uninitialized fields governed by an
atomic bit could be observed in advance due to memory reordering thus
memory barrier pairs should be used.
There is also a trivial fix of crafted blkszbits generated by
syzkaller.

- fix shift-out-of-bounds of crafted blkszbits generated by syzkaller

Pull f2fs updates from Jaegeuk Kim:
"We've added two major features: 1) compression level and 2)
checkpoint_merge, in this round.
Compression level expands 'compress_algorithm' mount option to accept
parameter as format of <algorithm>:<level>, by this way, it gives a
way to allow user to do more specified config on lz4 and zstd
compression level, then f2fs compression can provide higher compress
ratio.
checkpoint_merge creates a kernel daemon and makes it to merge
concurrent checkpoint requests as much as possible to eliminate
redundant checkpoint issues. Plus, we can eliminate the sluggish issue
caused by slow checkpoint operation when the checkpoint is done in a
process context in a cgroup having low i/o budget and cpu shares.
Enhancements:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fixes:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition

- preemptive background flushing: separate the logic from ticket
reservations, improve the accounting and decisions when to flush in
low space conditions
- less lock contention related to running delayed refs, let just one
thread do the flushing when there are many inside transaction
commit
- dbench workload improvements: avoid unnecessary work when logging
inodes, fewer fallbacks to transaction commit and thus less waiting
for it (+7% throughput, -20% latency)
Core:
- subpage block size
- currently read-only support
- refactor and generalize code where sectorsize is assumed to be
page size, add the subpage handling everywhere
- the read-write support is on the way, page sizes are still
limited to 4K or 64K
- zoned mode, first working version but with limitations
- SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed
location for structures" and chunked allocation
- superblock as the only fixed data structure needs special
handling, uses 2 consecutive zones as a ring buffer
- tree-log support with a dedicated block group to avoid unordered
writes
- emulated zones on non-zoned devices
- not yet working
- all non-single block group profiles, requires more zone write
pointer synchronization between the multiple block groups
- fitrim due to dependency on space cache, can be implemented
Fixes:
- ref-verify: proper tree owner and node level tracking
- fix pinned byte accounting, causing some early ENOSPC now more
likely due to other changes in delayed refs
Other:
- error handling fixes and improvements
- more error injection points
- more function documentation
- more and updated tracepoints
- subset of W=1 checked by default
- update comments to allow more automatic kdoc parameter checks"

Al root-caused a new warning from syzbot to the ttyprintk tty driver
returning a write count larger than the data the tty layer actually gave
it. Which confused the tty write code mightily, and with the new
iov_iter based code, caused a WARNING in iov_iter_revert().
syzbot correctly bisected the source of the new warning to commit
9bb48c82aced ("tty: implement write_iter"), but the oddity goes back
much further, it just didn't get caught by anything before.

Pull ARM SoC platform removals from Arnd Bergmann:
"There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use, and
received confirmation about six ARM platforms and the TI C6x
architecture that have all reached the end of their life upstream,
with no known users remaining:
- efm32 - added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell - added in 2011, abandoned after 2012 acquisition
- prima2 - added in 20111, no notable changes since 2015
- tango - added in 2015, sporadic changes until 2017, but abandoned
- u300 - added in 2009, no notable changes since 2013
- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users that
plan to contribute them in the future, in other cases the code is
complete and works reliably"
