Subject: [PATCH 01/10] vhost: remove work arg from vhost_work_flush
Date: Thu, 12 Nov 2020 23:19:01 +0000
Message-ID: <1605223150-10888-3-git-send-email-michael.christie@oracle.com> (raw)
In-Reply-To: <1605223150-10888-1-git-send-email-michael.christie@oracle.com>

vhost_work_flush doesn't do anything with the work arg. This patch drops
it and then renames vhost_work_flush to vhost_work_dev_flush to reflect
that the function flushes all the works in the dev and not just a
specific queue or work item.
