Merge tag 'xfs-5.12-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull more xfs updates from Darrick Wong:
 "The most notable fix here prevents premature reuse of freed metadata
  blocks, and adding the ability to detect accidental nested
  transactions, which are not allowed here.

   - Restore a disused sysctl control knob that was inadvertently
     dropped during the merge window to avoid fstests regressions.

   - Don't speculatively release freed blocks from the busy list until
     we're actually allocating them, which fixes a rare log recovery
     regression.

   - Don't nest transactions when scanning for free space.

   - Add an idiot^Wmaintainer light to detect nested transactions. ;)"
