From: Xiubo Li <xiubli@redhat.com>

Changed in V2:
- do not check the caps when reconnecting to mds
- switch ceph_async_check_caps() to ceph_async_put_cap_refs()


Xiubo Li (2):
  ceph: add ceph_async_put_cap_refs to avoid double lock and deadlock
  ceph: do not check the caps when reconnecting to mds
