+	  Some NFS servers support an auxiliary NFS LOCALIO protocol
+	  that is not an official part of the NFS protocol.
+
+	  This option enables support for the LOCALIO protocol in the
+	  kernel's NFS server and client. Enable this to permit local
+	  NFS clients to bypass the network when issuing reads and
+	  writes to the local NFS server.
+
+	  If unsure, say N.
