I think this looks good, but please move this before your changes (e.g. before patch 'virtio/vsock: dequeue callback for SOCK_SEQPACKET'). In this way you don't need to modify virtio_transport_notify_buffer_size(), calling virtio_transport_get_type() and then remove these changes. It's generally not a good idea to make changes in a patch and then remove them a few patches later in the same series. This should ring a bell about moving these changes before others.
