Hi all,
this series reworks handling of post-EOF blocks, primarily in ->release.
This takes over the work originally started by Dave in:
https://marc.info/?l=linux-xfs&m=154951612101291&w=2
and lingering in Darricks's tree:
https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git/log/?h=reduce-eofblocks-gc-on-close
for years to ensure ->release doesn't too eagerly kill post-EOF block
speculative preallocation and then goes on to not let preallocation
on inodes with the append only flag set linger forever.
Note that this does not include any of the suggested improvements for
i_flags_lock contention - that's left for a follow-on series.
Changes since v2:
- fix another typo
- use test and set semantics for XFS_EOFBLOCKS_RELEASED
Changes since v1:
- fix a few commit log and comment typos
