  ceph: flush dirty inodes before proceeding with remount (2019-05-07 19:43:05 +0200)

----------------------------------------------------------------
On the filesystem side we have:

- a fix to enforce quotas set above the mount point (Luis Henriques)

- support for exporting snapshots through NFS (Zheng Yan)

- proper statx implementation (Jeff Layton).  statx flags are mapped
  to MDS caps, with AT_STATX_{DONT,FORCE}_SYNC taken into account.

- some follow-up dentry name handling fixes, in particular elimination
  of our hand-rolled helper and the switch to __getname() as suggested
  by Al (Jeff Layton)

- a set of MDS client cleanups in preparation for async MDS requests
  in the future (Jeff Layton)

- a fix to sync the filesystem before remounting (Jeff Layton)

On the rbd side, work is on-going on object-map and fast-diff image
features.

----------------------------------------------------------------
