The flush after vhost_dev_cleanup is not needed because: 1. It doesn't do anything. vhost_dev_cleanup will stop the worker thread so the flush call will just return since the worker has not device. 2. It's not needed. The comment about jobs re-queueing themselves does not look correct because handle_vq does not requeue work. Signed-off-by: Mike Christie <michael.christie@xxxxxxxxxx>
