Merge tag 'xfs-5.15-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"There's a lot in this cycle.

Starting with bug fixes: To avoid livelocks between the logging code
and the quota code, we've disabled the ability of quotaoff to turn off
quota accounting. (Admins can still disable quota enforcement, but
truly turning off accounting requires a remount.) We've tried to do
this in a careful enough way that there shouldn't be any user visible
effects aside from quotaoff no longer randomly hanging the system.

We've also fixed some bugs in runtime log behavior that could trip up
log recovery if (otherwise unrelated) transactions manage to start and
commit concurrently; some bugs in the GETFSMAP ioctl where we would
incorrectly restrict the range of records output if the two xfs
devices are of different sizes; a bug that resulted in fallocate
funshare failing unnecessarily; and broken behavior in the xfs inode
cache when DONTCACHE is in play.

As for new features: we now batch inode inactivations in percpu
background threads, which sharply decreases frontend thread wait time
when performing file deletions and should improve overall directory
tree deletion times. This eliminates both the problem where closing an
unlinked file (especially on a frozen fs) can stall for a long time,
and should also ease complaints about direct reclaim bogging down on
unlinked file cleanup.

Starting with this release, we've enabled pipelining of the XFS log.
On workloads with high rates of metadata updates to different shards
of the filesystem, multiple threads can be used to format committed
log updates into log checkpoints.

Lastly, with this release, two new features have graduated to
supported status: inode btree counters (for faster mounts), and
support for dates beyond Y2038. Expect these to be enabled by default
in a future release of xfsprogs.

Summary:

- Fix a potential log livelock on busy filesystems when there's so
much work going on that we can't finish a quotaoff before filling
up the log by removing the ability to disable quota accounting.

- Introduce the ability to use per-CPU data structures in XFS so that
we can do a better job of maintaining CPU locality for certain
operations.

- Defer inode inactivation work to per-CPU lists, which will help us
batch that processing. Deletions of large sparse files will
*appear* to run faster, but all that means is that we've moved the
work to the backend.

- Drop the EXPERIMENTAL warnings from the y2038+ support and the
inode btree counters, since it's been nearly a year and no
complaints have come in.

- Remove more of our bespoke kmem* variants in favor of using the
standard Linux calls.

- Prepare for the addition of log incompat features in upcoming
cycles by actually adding code to support this.

- Small cleanups of the xattr code in preparation for landing support
for full logging of extended attribute updates in a future cycle.

- Replace the various log shutdown state and flag code all over xfs
with a single atomic bit flag.

- Fix a serious log recovery bug where log item replay can be skipped
based on the start lsn of a transaction even though the transaction
commit lsn is the key data point for that by enforcing start lsns
to appear in the log in the same order as commit lsns.

- Enable pipelining in the code that pushes log items to disk.

- Drop ->writepage.

- Fix some bugs in GETFSMAP where the last fsmap record reported for
a device could extend beyond the end of the device, and a separate
bug where query keys for one device could be applied to another.

- Don't let GETFSMAP query functions edit their input parameters.

- Small cleanups to the scrub code's handling of perag structures.

- Small cleanups to the incore inode tree walk code.

- Constify btree function parameters that aren't changed, so that
there will never again be confusion about range query functions
changing their input parameters.

- Standardize the format and names of tracepoint data attributes.

- Clean up all the mount state and feature flags to use wrapped
bitset functions instead of inconsistently open-coded flag checks.

- Fix some confusion between xfs_buf hash table key variable vs.
block number.

- Fix a mis-interaction with iomap where we reported shared delalloc
cow fork extents to iomap, which would cause the iomap unshare
operation to return IO errors unnecessarily.

- Fix DONTCACHE behavior"

xfs: convert remaining mount flags to state flags

The remaining mount flags kept in m_flags are actually runtime state
flags. These change dynamically, so they really should be updated
atomically so we don't potentially lose an update due to racing
modifications.

Convert these remaining flags to be stored in m_opstate and use
atomic bitops to set and clear the flags. This also adds a couple of
simple wrappers for common state checks - read only and shutdown.

xfs: replace xfs_sb_version checks with feature flag checks

Convert the xfs_sb_version_hasfoo() to checks against
mp->m_features. Checks of the superblock itself during disk
operations (e.g. in the read/write verifiers and the to/from disk
formatters) are not converted - they operate purely on the
superblock state. Everything else should use the mount features.

Large parts of this conversion were done with sed with commands like
this:

for f in `git grep -l xfs_sb_version_has fs/xfs/*.c`; do
sed -i -e 's/xfs_sb_version_has\(.*\)(&\(.*\)->m_sb)/xfs_has_\1(\2)/' $f
done

With manual cleanups for things like "xfs_has_extflgbit" and other
little inconsistencies in naming.

The result is ia lot less typing to check features and an XFS binary
size reduced by a bit over 3kB:

$ size -t fs/xfs/built-in.a

Merge tag 'xfs-5.14-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"Most of the work this cycle has been on refactoring various parts of
the codebase. The biggest non-cleanup changes are (1) reducing the
number of cache flushes sent when writing the log; (2) a substantial
number of log recovery fixes; and (3) I started accepting pull
requests from contributors if the commits in their branches match
what's been sent to the list.

For a week or so I /had/ staged a major cleanup of the logging code
from Dave Chinner, but it exposed so many lurking bugs in other parts
of the logging and log recovery code that I decided to defer that
patchset until we can address those latent bugs.

Larger cleanups this time include walking the incore inode cache (me)
and rework of the extended attribute code (Allison) to prepare it for
adding logged xattr updates (and directory tree parent pointers) in
future releases.

Summary:

- Refactor the buffer cache to use bulk page allocation

- Convert agnumber-based AG iteration to walk per-AG structures

- Clean up some unit conversions and other code warts

- Reduce spinlock contention in the directio fastpath

- Collapse all the inode cache walks into a single function

- Remove indirect function calls from the inode cache walk code

- Dramatically reduce the number of cache flushes sent when writing
log buffers

- Preserve inode sickness reports for longer

- Rename xfs_eofblocks since it controls inode cache walks

- Refactor the extended attribute code to prepare it for the addition
of log intent items to make xattrs fully transactional

- A few fixes to earlier large patchsets

- Log recovery fixes so that we don't accidentally mark the log clean
when log intent recovery fails

- Fix some latent SOB errors

- Clean up shutdown messages that get logged to dmesg

- Fix a regression in the online shrink code

- Fix a UAF in the buffer logging code if the fs goes offline

- Fix uninitialized error variables

- Fix a UAF in the CIL when commited log item callbacks race with a
shutdown

- Fix a bug where the CIL could hang trying to push part of the log
ring buffer that hasn't been filled yet"
