  ceph: fix potential bad pointer deref in async dirops cb's (2020-04-13 19:33:47 +0200)

----------------------------------------------------------------
A set of patches for a deadlock on "rbd map" error path and a fix
for invalid pointer dereference and uninitialized variable use on
asynchronous create and unlink error paths.

----------------------------------------------------------------
Ilya Dryomov (4):
      rbd: avoid a deadlock on header_rwsem when flushing notifies
      rbd: call rbd_dev_unprobe() after unwatching and flushing notifies
      rbd: don't test rbd_dev->opts in rbd_dev_image_release()
      rbd: don't mess with a page vector in rbd_notify_op_lock()
