		layout drivers
		--------------

		PNFS utilizes what is called layout drivers. The STD defines 3 basic
		layout types: "files" "objects" and "blocks". For each of these types
		there is a layout-driver with a common function-vectors table which
		are called by the nfs-client pnfs-core to implement the different layout
		types.
