  ceph: fix variable dereferenced before check in ceph_umount_begin() (2025-06-06 11:08:59 +0200)

----------------------------------------------------------------
A one-liner that leads to a startling (but also very much rational)
performance improvement in cases where an IMA policy with rules that
are based on fsmagic matching is enforced, an encryption-related fixup
that addresses generic/397 and other fstest failures and a couple of
cleanups in CephFS.

----------------------------------------------------------------
Dennis Marttinen (1):
      ceph: set superblock s_magic for IMA fsmagic matching

Dmitry Kandybka (1):
      ceph: fix possible integer overflow in ceph_zero_objects()

Viacheslav Dubeyko (3):
      ceph: avoid kernel BUG for encrypted inode with unaligned file size
      ceph: cleanup hardcoded constants of file handle size
      ceph: fix variable dereferenced before check in ceph_umount_begin()
