- 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.

Pull more xfs updates from Darrick Wong:
"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.

- 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
