[GIT PULL] xfs: new code for 5.15

From: Darrick J. Wong
Date: Tue Aug 31 2021 - 17:18:59 EST

Hi Linus,

Please pull this branch containing new code for 5.15. 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.

The branch merges cleanly against upstream as of a few minutes ago.
Please let me know if anything else strange happens during the merge
process.

xfs: fix I_DONTCACHE (2021-08-24 19:13:04 -0700)

----------------------------------------------------------------
New code for 5.15:
- 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.
