This patchset implements the current proposal for virtio cross-device
resource sharing [1], with minor changes based on recent comments. It
is expected that this will be used to import virtio resources into the
virtio-video driver currently under discussion [2].

This patchset adds a new hook to dma-buf, for querying the dma-buf's
underlying virtio UUID. This hook is then plumbed through DRM PRIME
buffers, and finally implemented in virtgpu.

Looks all fine to me.  We should wait for the virtio protocol update
(patch 3/4) being accepted into the virtio specification.  When this is
done I'll go commit this to drm-misc-next.

cheers,
