 Recalling the first round of new code for 5.10, in which we added:
 - New feature: Widen inode timestamps and quota grace expiration
   timestamps to support dates through the year 2486.
 - New feature: storing inode btree counts in the AGI to speed up certain
   mount time per-AG block reservation operatoins and add a little more
   metadata redundancy.
 
 For the second round of new code for 5.10:
 - Deprecate the V4 filesystem format, some disused mount options, and some
   legacy sysctl knobs now that we can support dates into the 25th century.
   Note that removal of V4 support will not happen until the early 2030s.
 - Fix some probles with inode realtime flag propagation.
 - Fix some buffer handling issues when growing a rt filesystem.
 - Fix a problem where a BMAP_REMAP unmap call would free rt extents even
   though the purpose of BMAP_REMAP is to avoid freeing the blocks.
 - Strengthen the dabtree online scrubber to check hash values on child
   dabtree blocks.
 - Actually log new intent items created as part of recovering log intent
   items.
 - Fix a bug where quotas weren't attached to an inode undergoing bmap
   intent item recovery.
 - Fix a buffer overrun problem with specially crafted log buffer
   headers.
 - Various cleanups to type usage and slightly inaccurate comments.
 - More cleanups to the xattr, log, and quota code.
 - Don't run the (slower) shared-rmap operations on attr fork mappings.
 - Fix a bug where we failed to check the LSN of finobt blocks during
   replay and could therefore overwrite newer data with older data.
 - Clean up the ugly nested transaction mess that log recovery uses to
   stage intent item recovery in the correct order by creating a proper
   data structure to capture recovered chains.
 - Use the capture structure to resume intent item chains with the
   same log space and block reservations as when they were captured.
 - Fix a UAF bug in bmap intent item recovery where we failed to maintain
   our reference to the incore inode if the bmap operation needed to
   relog itself to continue.
 - Rearrange the defer ops mechanism to finish newly created subtasks
   of a parent task before moving on to the next parent task.
 - Automatically relog intent items in deferred ops chains if doing so
   would help us avoid pinning the log tail.  This will help fix some
   log scaling problems now and will facilitate atomic file updates later.
 - Fix a deadlock in the GETFSMAP implementation by using an internal
   memory buffer to reduce indirect calls and copies to userspace,
   thereby improving its performance by ~20%.
 - Fix various problems when calling growfs on a realtime volume would
   not fully update the filesystem metadata.
 - Fix broken Kconfig asking about deprecated XFS when XFS is disabled.

 "The second large pile of new stuff for 5.10, with changes even more
  monumental than last week!

  We are formally announcing the deprecation of the V4 filesystem format
  in 2030. All users must upgrade to the V5 format, which contains
  design improvements that greatly strengthen metadata validation,
  supports reflink and online fsck, and is the intended vehicle for
  handling timestamps past 2038. We're also deprecating the old Irix
  behavioral tweaks in September 2025.

  Coming along for the ride are two design changes to the deferred
  metadata ops subsystem. One of the improvements is to retain correct
  logical ordering of tasks and subtasks, which is a more logical design
  for upper layers of XFS and will become necessary when we add atomic
  file range swaps and commits. The second improvement to deferred ops
  improves the scalability of the log by helping the log tail to move
  forward during long-running operations. This reduces log contention
  when there are a large number of threads trying to run transactions.

  In addition to that, this fixes numerous small bugs in log recovery;
  refactors logical intent log item recovery to remove the last
  remaining place in XFS where we could have nested transactions; fixes
  a couple of ways that intent log item recovery could fail in ways that
  wouldn't have happened in the regular commit paths; fixes a deadlock
  vector in the GETFSMAP implementation (which improves its performance
  by 20%); and fixes serious bugs in the realtime growfs, fallocate, and
  bitmap handling code.

  Summary:

   - Deprecate the V4 filesystem format, some disused mount options, and
     some legacy sysctl knobs now that we can support dates into the
     25th century. Note that removal of V4 support will not happen until
     the early 2030s.

   - Fix some probles with inode realtime flag propagation.

   - Fix some buffer handling issues when growing a rt filesystem.

   - Fix a problem where a BMAP_REMAP unmap call would free rt extents
     even though the purpose of BMAP_REMAP is to avoid freeing the
     blocks.

   - Strengthen the dabtree online scrubber to check hash values on
     child dabtree blocks.

   - Actually log new intent items created as part of recovering log
     intent items.

   - Fix a bug where quotas weren't attached to an inode undergoing bmap
     intent item recovery.

   - Fix a buffer overrun problem with specially crafted log buffer
     headers.

   - Various cleanups to type usage and slightly inaccurate comments.

   - More cleanups to the xattr, log, and quota code.

   - Don't run the (slower) shared-rmap operations on attr fork
     mappings.

   - Fix a bug where we failed to check the LSN of finobt blocks during
     replay and could therefore overwrite newer data with older data.

   - Clean up the ugly nested transaction mess that log recovery uses to
     stage intent item recovery in the correct order by creating a
     proper data structure to capture recovered chains.

   - Use the capture structure to resume intent item chains with the
     same log space and block reservations as when they were captured.

   - Fix a UAF bug in bmap intent item recovery where we failed to
     maintain our reference to the incore inode if the bmap operation
     needed to relog itself to continue.

   - Rearrange the defer ops mechanism to finish newly created subtasks
     of a parent task before moving on to the next parent task.

   - Automatically relog intent items in deferred ops chains if doing so
     would help us avoid pinning the log tail. This will help fix some
     log scaling problems now and will facilitate atomic file updates
     later.

   - Fix a deadlock in the GETFSMAP implementation by using an internal
