ceph: fix file lock interruption
When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng <zyan@redhat.com>
