Subject: [PATCH 04/10] ublk: don't get ublk device reference in ublk_abort_queue()
Date: Mon, 18 Sep 2023 12:11:00 +0800 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
ublk_abort_queue() is called in ublk_daemon_monitor_work(), in which
it is guaranteed that ublk device is live, so no need to get the device
reference.
