  ceph: stop on-going cached readdir if mds revokes FILE_SHARED cap (2017-09-06 19:57:00 +0200)

----------------------------------------------------------------
The highlights include:

 * a large series of fixes and improvements to the snapshot-handling
   code (Zheng Yan)

 * individual read/write OSD requests passed down to libceph are now
   limited to 16M in size to avoid hitting OSD-side limits (Zheng Yan)

 * encode MStatfs v2 message to allow for more accurate space usage
   reporting (Douglas Fuller)

 * switch to the new writeback error tracking infrastructure (Jeff
   Layton)
