  gfs2: harden gfs2_glock_hold (2026-08-12 20:22:51 +0200)

----------------------------------------------------------------
gfs2 changes

- Don't cache unreferenced glocks: when a glock is no longer referenced (for
  example, because the inode it protects is evicted), it is now released as
  soon as possible instead of leaving it around until memory pressure or an
  unmount forces it out.  For some workloads, this saves a lot of memory and
  speeds up unmounts significantly.

- Harden gfs2_glock_hold() by making sure the caller holds a reference and
  fix a related race in checking for the liveliness of glocks between
  gdlm_bast() and gfs2_glock_cb().

I should have pointed out the conflict between commit

91e27ed8a387c ("lockref: tidy up dead count handling")

from Christian Brauner's pull request for tag kernel-7.3-rc1.misc [*]
tag and the following two commits from this gfs2 pull request:

da26828b82a45 ("gfs2: Remove the glock lru list and shrinker")
657e5af4fe0b9 ("gfs2: harden gfs2_glock_hold")

As Christian points out in his pull request, the conflicts are caused
by the renaming of __lockref_is_dead() to lockref_is_dead() in commit
91e27ed8a387c.

Thanks,
