  ceph: add a new metric to keep track of remote object copies (2021-11-08 03:29:52 +0100)

----------------------------------------------------------------
One notable change here is that async creates and unlinks introduced
in 5.7 are now enabled by default.  This should greatly speed up things
like rm, tar and rsync.  To opt out, wsync mount option can be used.

Other than that we have a pile of bug fixes all across the filesystem
from Jeff, Xiubo and Kotresh and a metrics infrastructure rework from
Luis.

----------------------------------------------------------------
Jean Sacren (1):
      libceph: drop ->monmap and err initialization

Jeff Layton (11):
      ceph: convert to noop_direct_IO
      ceph: enable async dirops by default
      ceph: print inode numbers instead of pointer values
      ceph: don't use -ESTALE as special return code in try_get_cap_refs
      ceph: drop private list from remove_session_caps_cb
      ceph: fix auth cap handling logic in remove_session_caps_cb
      ceph: refactor remove_session_caps_cb
      ceph: shut down access to inode when async create fails
      ceph: just use ci->i_version for fscache aux info
      ceph: shut down mount on bad mdsmap or fsmap decode
      ceph: properly handle statfs on multifs setups

Kotresh HR (1):
      ceph: don't rely on error_string to validate blocklisted session.

Luis Henriques (4):
      ceph: split 'metric' debugfs file into several files
      ceph: clean-up metrics data structures to reduce code duplication
      libceph, ceph: move ceph_osdc_copy_from() into cephfs code
      ceph: add a new metric to keep track of remote object copies

Xiubo Li (3):
      ceph: ignore the truncate when size won't change with Fx caps issued
      ceph: fix mdsmap decode when there are MDS's beyond max_mds
      ceph: return the real size read when it hits EOF
