[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.
[akpm@osdl.org: cleanups, build fix]
