Subject: [PATCH V3 2/8] vhost: flush dev once during vhost_dev_stop
Date: Tue, 17 May 2022 13:08:44 -0500 [thread overview]
Message-ID: <20220517180850.198915-3-michael.christie@oracle.com> (raw)
In-Reply-To: <20220517180850.198915-1-michael.christie@oracle.com>
When vhost_work_dev_flush returns all work queued at that time will have
completed. There is then no need to flush after every vhost_poll_stop
call, and we can move the flush call to after the loop that stops the
pollers.
