ceph: fix dereference of null pointer cf (2021-09-03 10:55:51 +0200)

----------------------------------------------------------------
We have:

- a set of patches to address fsync stalls caused by depending on
periodic rather than triggered MDS journal flushes in some cases
(Xiubo Li)

- a fix for mtime effectively not getting updated in case of competing
writers (Jeff Layton)

- a couple of fixes for inode reference leaks and various WARNs after
"umount -f" (Xiubo Li)

- a new ceph.auth_mds extended attribute (Jeff Layton)

- a smattering of fixups and cleanups from Jeff, Xiubo and Colin.
