Linus Torvalds 5631c5e0eb New code for 5.9:
- 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-5.9-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

     warning counter limits set by the administrator.
