#     Merge tag 'ceph-for-5.4-rc1' of git://github.com/ceph/ceph-client
#     
#     Pull ceph updates from Ilya Dryomov:
#      "The highlights are:
#     
#        - automatic recovery of a blacklisted filesystem session (Zheng Yan).
#          This is disabled by default and can be enabled by mounting with the
#          new "recover_session=clean" option.
#     
#        - serialize buffered reads and O_DIRECT writes (Jeff Layton). Care is
#          taken to avoid serializing O_DIRECT reads and writes with each
#          other, this is based on the exclusion scheme from NFS.
#     
#        - handle large osdmaps better in the face of fragmented memory
#          (myself)
#     
#        - don't limit what security.* xattrs can be get or set (Jeff Layton).
#          We were overly restrictive here, unnecessarily preventing things
#          like file capability sets stored in security.capability from
#          working.
#     
#        - allow copy_file_range() within the same inode and across different
#          filesystems within the same cluster (Luis Henriques)"
#
