This patch use the tag name in the config space to identify the mount device. The the virtio device name depend on the enumeration order of the device and may not remain the same across multiple boots So we use the tag name which is set via qemu option to uniquely identify the mount device Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
