From 80212d59e32a8a8e030c2ddc5861d8ff70542c56 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 2 Oct 2006 02:17:47 -0700 Subject: [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.
