  ceph: avoid fs reclaim while using current->journal_info (2026-07-23 20:29:42 +0200)

----------------------------------------------------------------
A bunch of assorted fixes with the majority being hardening against
malformed input and invalid data scenarios that don't happen in real
deployments but can be utilized to trigger use-after-free and similar
issues, some error path leak fixups and two patches from Max to avoid
a potential hang in __ceph_get_caps() and unintended nesting of
current->journal_info while handling replies from the MDS.  All marked
for stable.
