Subject: [PATCH 0/3] rbd: fix some issues around flushing notifies
Date: Tue, 17 Mar 2020 13:04:19 +0100 [thread overview]
Message-ID: <20200317120422.3406-1-idryomov@gmail.com> (raw)
Hello,
A recent snapshot-based mirroring experiment exposed a deadlock on
header_rwsem in the error path of rbd_dev_image_probe() (i.e. "rbd
map").
Thanks,
Ilya
Ilya Dryomov (3):
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()
