  ceph: fix NULL pointer dereference in ceph_mds_auth_match() (2026-02-04 22:00:42 +0100)

----------------------------------------------------------------
One RBD and two CephFS fixes which address potential oopses.  The RBD
thing is more of a rare edge case that pops up in our CI, while the two
CephFS scenarios are regressions that were reported by users and can be
triggered trivially in normal operation.  All marked for stable.
