  ceph: add bug tracking system info to MAINTAINERS (2025-10-09 00:15:04 +0200)

----------------------------------------------------------------
Some messenger improvements from Eric and Max, a patch to address the
issue (also affected userspace) of incorrect permissions being granted
to users who have access to multiple different CephFS instances within
the same cluster from Kotresh and a bunch of assorted CephFS fixes from
Slava.

----------------------------------------------------------------
Eric Biggers (1):
      libceph: Use HMAC-SHA256 library instead of crypto_shash

Kotresh HR (1):
      ceph: fix multifs mds auth caps issue

Max Kellermann (4):
      ceph: make ceph_start_io_*() killable
      libceph: make ceph_con_get_out_msg() return the message pointer
      libceph: pass the message pointer instead of loading con->out_msg
      libceph: add empty check to ceph_con_get_out_msg()

Viacheslav Dubeyko (9):
      ceph: add checking of wait_for_completion_killable() return value
      ceph: fix wrong sizeof argument issue in register_session()
      ceph: fix overflowed constant issue in ceph_do_objects_copy()
