New code for 5.7:

- 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.

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.
