This version rebased on Rusty's virtio ring rework patches. We hope this can go into virtio-next together with the virtio ring rework pathes. V4: rebase on virtio ring rework patches (rusty's pending-rebases branch) V3 and be found http://marc.info/?l=linux-virtualization&m=136067440717154&w=2 It would probably be easier to get it in via Rusty's tree because of the prerequisites. James, can we get your Acked-by?
