Merge tag 'v6.6-vfs.ctime' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs timestamp updates from Christian Brauner:
"This adds VFS support for multi-grain timestamps and converts tmpfs,
xfs, ext4, and btrfs to use them. This carries acks from all relevant
filesystems.

The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot of metadata updates, down to around 1 per
jiffy, even when a file is under heavy writes.

Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache.

Even with NFSv4, a lot of exported filesystems don't properly support
a change attribute and are subject to the same problems with timestamp
granularity. Other applications have similar issues with timestamps
(e.g., backup applications).

If we were to always use fine-grained timestamps, that would improve
the situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.

This introduces fine-grained timestamps that are used when they are
actively queried.

This uses the 31st bit of the ctime tv_nsec field to indicate that
something has queried the inode for the mtime or ctime. When this flag
is set, on the next mtime or ctime update, the kernel will fetch a
fine-grained timestamp instead of the usual coarse-grained one.

As POSIX generally mandates that when the mtime changes, the ctime
must also change the kernel always stores normalized ctime values, so
only the first 30 bits of the tv_nsec field are ever used.

Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.

Various preparatory changes, fixes and cleanups are included:

- Fixup all relevant places where POSIX requires updating ctime
together with mtime. This is a wide-range of places and all
maintainers provided necessary Acks.

- Add new accessors for inode->i_ctime directly and change all
callers to rely on them. Plain accesses to inode->i_ctime are now
gone and it is accordingly rename to inode->__i_ctime and commented
as requiring accessors.

- Extend generic_fillattr() to pass in a request mask mirroring in a
sense the statx() uapi. This allows callers to pass in a request
mask to only get a subset of attributes filled in.

- Rework timestamp updates so it's possible to drop the @now
parameter the update_time() inode operation and associated helpers.

- Add inode_update_timestamps() and convert all filesystems to it
removing a bunch of open-coding"

ext4: reject casefold inode flag without casefold feature

It is invalid for the casefold inode flag to be set without the casefold
superblock feature flag also being set. e2fsck already considers this
case to be invalid and handles it by offering to clear the casefold flag
on the inode. __ext4_iget() also already considered this to be invalid,
sort of, but it only got so far as logging an error message; it didn't
actually reject the inode. Make it reject the inode so that other code
doesn't have to handle this case. This matches what f2fs does.

Note: we could check 's_encoding != NULL' instead of
ext4_has_feature_casefold(). This would make the check robust against
the casefold feature being enabled by userspace writing to the page
cache of the mounted block device. However, it's unsolvable in general
for filesystems to be robust against concurrent writes to the page cache
of the mounted block device. Though this very particular scenario
involving the casefold feature is solvable, we should not pretend that
we can support this model, so let's just check the casefold feature.
tune2fs already forbids enabling casefold on a mounted filesystem.

ext4: do not mark inode dirty every time when appending using delalloc

In the delalloc append write scenario, if inode's i_size is extended due
to buffer write, there are delalloc writes pending in the range up to
i_size, and no need to touch i_disksize since writeback will push
i_disksize up to i_size eventually. Offers significant performance
improvement in high-frequency append write scenarios.

I conducted tests in my 32-core environment by launching 32 concurrent
threads to append write to the same file. Each write operation had a
length of 1024 bytes and was repeated 100000 times. Without using this
patch, the test was completed in 7705 ms. However, with this patch, the
test was completed in 5066 ms, resulting in a performance improvement of
34%.

Moreover, in test scenarios of Kafka version 2.6.2, using packet size of
2K, with this patch resulted in a 10% performance improvement.

fs: pass the request_mask to generic_fillattr

generic_fillattr just fills in the entire stat struct indiscriminately
today, copying data from the inode. There is at least one attribute
(STATX_CHANGE_COOKIE) that can have side effects when it is reported,
and we're looking at adding more with the addition of multigrain
timestamps.

Add a request_mask argument to generic_fillattr and have most callers
just pass in the value that is passed to getattr. Have other callers
(e.g. ksmbd) just pass in STATX_BASIC_STATS. Also move the setting of
STATX_CHANGE_COOKIE into generic_fillattr.

EXT4_MF_FS_ABORTED flag has practically the same intent as

where we were relying on SB_RDONLY checks instead of the aborted flag
checks. There are only three places - ext4_sync_file(),
__ext4_remount(), and mballoc debug code - which check aborted flag and

Pull mm updates from Andrew Morton:

- Yosry Ahmed brought back some cgroup v1 stats in OOM logs

- Yosry has also eliminated cgroup's atomic rstat flushing

- Nhat Pham adds the new cachestat() syscall. It provides userspace
with the ability to query pagecache status - a similar concept to
mincore() but more powerful and with improved usability

- Mel Gorman provides more optimizations for compaction, reducing the
prevalence of page rescanning

- Lorenzo Stoakes has done some maintanance work on the
get_user_pages() interface

- Liam Howlett continues with cleanups and maintenance work to the
maple tree code. Peng Zhang also does some work on maple tree

- Johannes Weiner has done some cleanup work on the compaction code

- David Hildenbrand has contributed additional selftests for
get_user_pages()

- Thomas Gleixner has contributed some maintenance and optimization
work for the vmalloc code

- Baolin Wang has provided some compaction cleanups,

- SeongJae Park continues maintenance work on the DAMON code

- Huang Ying has done some maintenance on the swap code's usage of
device refcounting

- Christoph Hellwig has some cleanups for the filemap/directio code

- Ryan Roberts provides two patch series which yield some
rationalization of the kernel's access to pte entries - use the
provided APIs rather than open-coding accesses

- Lorenzo Stoakes has some fixes to the interaction between pagecache
and directio access to file mappings

- John Hubbard has a series of fixes to the MM selftesting code

- ZhangPeng continues the folio conversion campaign

- Hugh Dickins has been working on the pagetable handling code, mainly
with a view to reducing the load on the mmap_lock

- Catalin Marinas has reduced the arm64 kmalloc() minimum alignment
from 128 to 8

- Domenico Cerasuolo has improved the zswap reclaim mechanism by
reorganizing the LRU management

- Matthew Wilcox provides some fixups to make gfs2 work better with the
buffer_head code

- Vishal Moola also has done some folio conversion work

- Matthew Wilcox has removed the remnants of the pagevec code - their
functionality is migrated over to struct folio_batch

Refactor VFP support code and reimplement in C

The VFP related changes to permit kernel mode NEON in softirq context
resulted in some issues regarding en/disabling of sofirqs from asm code,
and this made it clear that it would be better to handle more of it from
C code.

Given that we already have infrastructure that associates undefined
instruction exceptions with handler code based on value/mask pairs, we
can easily move the dispatch of VFP and NEON instructions to C code once
we reimplement the actual VFP support routine (which reasons about how
to deal with the exception and whether any emulation is needed) in C
code first.

With those out of the way, we can drop the partial decoding logic in asm
that reasons about which ISA is being used by user space, as the
remaining cases are all 32-bit ARM only. This leaves a FPE specific
routine with some iWMMXT logic that is easily duplicated in C as well,
allowing us to move the FPE asm code into the FPE asm source file, and
out of the shared entry code.
