Since you have this patch, I think you can generalize the title, update
the description, and merge here the changes I mentioned in patch 11/22
about changes of include/uapi/linux/virtio_vsock.h.

So you can have a single patch with the new virtio-spec defines and
structs related to SEQPACKET, of course then we move it before patch 11.

What do you think?
