Subject: [PATCH V2 8/8] vhost: rename vhost_work_dev_flush
Date: Sun, 15 May 2022 15:29:22 -0500	[thread overview]
Message-ID: <20220515202922.174066-9-michael.christie@oracle.com> (raw)
In-Reply-To: <20220515202922.174066-1-michael.christie@oracle.com>

This patch renames vhost_work_dev_flush to just vhost_dev_flush to
relfect that it flushes everything on the device and that drivers
don't know/care that polls are based on vhost_works. Drivers just
flush the entire device and polls, and works for vhost-scsi
management TMFs and IO net virtqueues, etc all are flushed.
