  ceph: cleanup pool op strings
  ceph: Use kzalloc
  ceph: use common helper for aborted dir request invalidation
  ceph: cope with out of order (unsafe after safe) mds reply
  ceph: save peer feature bits in connection structure
  ceph: resync headers with userland
  ceph: use ceph. prefix for virtual xattrs
  ceph: throw out dirty caps metadata, data on session teardown
  ceph: attempt mds reconnect if mds closes our session
  ceph: clean up send_mds_reconnect interface
  ceph: wait for mds OPEN reply to indicate reconnect success
  ceph: only send cap releases when mds is OPEN|HUNG
  ceph: dicard cap releases on mds restart
