This change adds a new flavor of dma-bufs that can be used by virtio drivers to share exported objects. A virtio dma-buf can be queried by virtio drivers to obtain the UUID which identifies the underlying exported object.

That duplicates a bunch of code from dma-buf.c in virtio_dma_buf.c.

How about dma_buf_{get,set}_uuid, simliar to dma_buf_set_name?
