* virtio: add dma-buf support for exported objectsDavid Stevens2020-08-181-0/+85
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. Signed-off-by: David Stevens <> Acked-by: Michael S.
