> This patch adds 'module' member in the 'struct vsock_transport'
> in order to get/put the transport module. This prevents the
> module unloading while sockets are assigned to it.
> 
> We increase the module refcnt when a socket is assigned to a
> transport, and we decrease the module refcnt when the socket
> is destructed.
