help
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.
