  ceph: allow idmapped mounts (2023-11-03 23:28:34 +0100)

There are a few conflicts in fs/ceph/inode.c caused by a clash between
the conversion to new timestamp accessors in VFS and logging changes in
CephFS.  I have the resolution in for-linus-merged, it's the same as in
linux-next.

----------------------------------------------------------------
Two items:

- support for idmapped mounts in CephFS (Christian Brauner, Alexander
  Mikhalitsyn).  The series was originally developed by Christian and
  later picked up and brought over the finish line by Alexander, who
  also contributed an enabler on the MDS side (separate owner_{u,g}id
  fields on the wire).  The required exports for mnt_idmap_{get,put}()
  in VFS have been acked by Christian and received no objection from
  Christoph.

- a churny change in CephFS logging to include cluster and client
  identifiers in log and debug messages (Xiubo Li).  This would help
  in scenarios with dozens of CephFS mounts on the same node which are
  getting increasingly common, especially in the Kubernetes world.
