Subject: [Qemu-devel] [PULL 10/16] virtio-scsi: convert to virtqueue_map
Date: Thu, 29 Oct 2015 11:39:47 +0200	[thread overview]
Message-ID: <1446111531-5755-11-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1446111531-5755-1-git-send-email-mst@redhat.com>

Note: virtqueue_map already validates input
so virtio-scsi does not have to.
