'virtio_transport_send_credit_update()' has some extra args:
1) 'type' may be set in 'virtio_transport_send_pkt_info()' using type
   of socket.
2) This function is static and 'hdr' arg was always NULL.

Okay, I saw this patch after my previous comment.

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.

Thanks,
Stefano
