Hello,

This came out of snapshot-based mirroring work.  Patches 1 and 2 are
preparatory, patch 3 fixes the issue (in as much as reasonable).

v1 -> v2:
- ceph_addr_is_blank() was missing an export
- amended locker equality semantics to ignore addr->type and moved the
  function to rbd.c

Thanks,

                Ilya


Ilya Dryomov (3):
  rbd: make get_lock_owner_info() return a single locker or NULL
  rbd: harden get_lock_owner_info() a bit
  rbd: retrieve and check lock owner twice before blocklisting
