Hi -
Can we allocate an official device major number for virtio devices? Currently it's using 240-254 (LOCAL/EXPERIMENTAL USE). The reason we ask for this is because userspace will need to treat virtio block devices differently and need a way to detect such device. For example, it checks major number to detect scsi and mmc device.

With dynamic major numbers 240-254, we might treat other devices as virtio block device incorrectly.
Also open for suggestions on what's the correct way to handle this.
Thanks in advance! jin
