Subject: [Qemu-devel] [PATCH v6 07/16] virtio-ccw: using VIRTIO_NO_VECTOR instead of 0 for invalid virtqueue
Date: Fri, 17 Apr 2015 12:48:31 +0800 [thread overview]
Message-ID: <1429246120-29439-8-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1429246120-29439-1-git-send-email-jasowang@redhat.com>
There's no need to use vector 0 for invalid virtqueue. So this patch
changes to use VIRTIO_NO_VECTOR instead.
