Merge tag 'ceph-for-6.7-rc1' of https://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:

 - 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.
