[PATCH 0/3] rbd: exclusive mapping (-o exclusive) fixes

[Ilya Dryomov <idryomov@xxxxxxxxx>]

Hello,

This addresses incorrect assumptions on rbd_dev->lock_state in
rbd_img_exclusive_lock() and rbd_add_acquire_lock() which could lead to
issues with exclusive mappings in the face of watch errors.

Thanks,

                Ilya


Ilya Dryomov (3):
  rbd: rename RBD_LOCK_STATE_RELEASING and releasing_wait
  rbd: don't assume RBD_LOCK_STATE_LOCKED for exclusive mappings
  rbd: don't assume rbd_is_lock_owner() for exclusive mappings
