	  RNBD client is a network block device driver using rdma transport.

	  RNBD client allows for mapping of a remote block devices over
	  RTRS protocol from a target system where RNBD server is running.

	  RNBD server is the server side of RNBD using rdma transport.

	  RNBD server allows for exporting local block devices to a remote client
	  over RTRS protocol.

	  If unsure, say N.
