Subject: [PATCH v4 24/25] virtio_scsi: drop scan callback
Date: Mon, 13 Oct 2014 10:51:44 +0300	[thread overview]
Message-ID: <1413114332-626-25-git-send-email-mst-v4@redhat.com> (raw)
In-Reply-To: <1413114332-626-1-git-send-email-mst-v4@redhat.com>

Enable VQs early like we do for restore.
This makes it possible to drop the scan callback,
moving scanning into the probe function, and making
code simpler.
