Merge tag 'xfs-5.9-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"There are quite a few changes in this release, the most notable of
which is that we've made inode flushing fully asynchronous, and we no
longer block memory reclaim on this.

Furthermore, we have fixed a long-standing bug in the quota code where
soft limit warnings and inode limits were never tracked properly.

Moving further down the line, the reflink control loops have been
redesigned to behave more efficiently; and numerous small bugs have
been fixed (see below). The xattr and quota code have been extensively
refactored in preparation for more new features coming down the line.

Finally, the behavior of DAX between ext4 and xfs has been stabilized,
which gets us a step closer to removing the experimental tag from that
feature.

We have a few new contributors this time around. Welcome, all!

I anticipate a second pull request next week for a few small bugfixes
that have been trickling in, but this is it for big changes.

Summary:

- Fix some btree block pingponging problems when swapping extents

- Redesign the reflink copy loop so that we only run one remapping
operation per transaction. This helps us avoid running out of block
reservation on highly deduped filesystems.

- Take the MMAPLOCK around filemap_map_pages.

- Make inode reclaim fully async so that we avoid stalling processes
on flushing inodes to disk.

- Reduce inode cluster buffer RMW cycles by attaching the buffer to
dirty inodes so we won't let go of the cluster buffer when we know
we're going to need it soon.

- Add some more checks to the realtime bitmap file scrubber.

- Don't trip false lockdep warnings in fs freeze.

- Remove various redundant lines of code.

- Remove unnecessary calls to xfs_perag_{get,put}.

- Preserve I_VERSION state across remounts.

- Fix an unmount hang due to AIL going to sleep with a non-empty
delwri buffer list.

- Fix an error in the inode allocation space reservation macro that
caused regressions in generic/531.

- Fix a potential livelock when dquot flush fails because the dquot
buffer is locked.

- Fix a miscalculation when reserving inode quota that could cause
users to exceed a hardlimit.

- Refactor struct xfs_dquot to use native types for incore fields
instead of abusing the ondisk struct for this purpose. This will
eventually enable proper y2038+ support, but for now it merely
cleans up the quota function declarations.

- Actually increment the quota softlimit warning counter so that soft
failures turn into hard(er) failures when they exceed the softlimit
warning counter limits set by the administrator.

- Split incore dquot state flags into their own field and namespace,
to avoid mixing them with quota type flags.

- Create a new quota type flags namespace so that we can make it
obvious when a quota function takes a quota type (user, group,
project) as an argument.

- Rename the ondisk dquot flags field to type, as that more
accurately represents what we store in it.

- Drop our bespoke memory allocation flags in favor of GFP_*.

- Rearrange the xattr functions so that we no longer mix metadata
updates and transaction management (e.g. rolling complex
transactions) in the same functions. This work will prepare us for
atomic xattr operations (itself a prerequisite for directory
backrefs) in future release cycles.

- Support FS_DAX_FL (aka FS_XFLAG_DAX) via GETFLAGS/SETFLAGS"

Merge tag 'xfs-5.7-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"There's a lot going on this cycle with cleanups in the log code, the
btree code, and the xattr code.

We're tightening of metadata validation and online fsck checking, and
introducing a common btree rebuilding library so that we can refactor
xfs_repair and introduce online repair in a future cycle.

We also fixed a few visible bugs -- most notably there's one in
getdents that we introduced in 5.6; and a fix for hangs when disabling
quotas.

This series has been running fstests & other QA in the background for
over a week and looks good so far.

I anticipate sending a second pull request next week. That batch will
change how xfs interacts with memory reclaim; how the log batches and
throttles log items; how hard writes near ENOSPC will try to squeeze
more space out of the filesystem; and hopefully fix the last of the
umount hangs after a catastrophic failure. That should ease a lot of
problems when running at the limits, but for now I'm leaving that in
for-next for another week to make sure we got all the subtleties
right.

Summary:

- Fix a hard to trigger race between iclog error checking and log
shutdown.

- Strengthen the AGF verifier.

- Ratelimit some of the more spammy error messages.

- Remove the icdinode uid/gid members and just use the ones in the
vfs inode.

- Hold ILOCK across insert/collapse range.

- Clean up the extended attribute interfaces.

- Clean up the attr flags mess.

- Restore PF_MEMALLOC after exiting xfsaild thread to avoid
triggering warnings in the process accounting code.

- Remove the flexibly-sized array from struct xfs_agfl to eliminate
compiler warnings about unaligned pointers and packed structures.

- Various macro and typedef removals.

- Stale metadata buffers if we decide they're corrupt outside of a
verifier.

- Check directory data/block/free block owners.

- Fix a UAF when aborting inactivation of a corrupt xattr fork.

- Teach online scrub to report failed directory and attr name lookups
as a metadata corruption instead of a runtime error.

- Avoid potential buffer overflows in sysfs files by using scnprintf.

- Fix a regression in getdents lookups due to a mistake in pointer
arithmetic.

- Refactor btree cursor private data structures to use anonymous
unions.

- Cleanups in the log unmounting code.

- Fix a potential mishandling of ENOMEM errors on multi-block
directory buffer lookups.

- Fix an incorrect test in the block allocation code.

- Cleanups and name prefix shortening in the scrub code.

- Introduce btree bulk loading code for online repair and scrub.

- Fix a quotaoff log item leak (and hang) when the fs goes down
midway through a quotaoff operation.

- Remove di_version from the incore inode.

- Refactor some of the log shutdown checking code.

- Record the forcing of the log unmount records in the log force
counters.

- Fix a longstanding bug where quotacheck would purge the
administrator's default quota grace interval and warning limits.

- Reduce memory usage when scrubbing directory and xattr trees.

- Don't let fsfreeze race with GETFSMAP or online scrub.

- Handle bio_add_page failures more gracefully in xlog_write_iclog"
