[PATCH] knfsd: define new nfsdfs file: portlist - contains list of ports
This file will list all ports that nfsd has open. Default when TCP enabled will be ipv4 udp 0.0.0.0 2049 ipv4 tcp 0.0.0.0 2049 Later, the list of ports will be settable. 'portlist' chosen rather than 'ports', to avoid unnecessary confusion with non-mainline patches which created 'ports' with different semantics.
