Subject: [PATCH 0/3] rbd: exclusive mapping (-o exclusive) fixes
Date: Wed, 24 Jul 2024 08:29:08 +0200	[thread overview]
Message-ID: <20240724062914.667734-1-idryomov@gmail.com> (raw)

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

  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
