problems with nfs-server in 2.5 bk as of 030115

Hi Trond,

This is the first time I've tried running an nfs-server in 2.5 and I
believe the problem I'm seeing is caused by your recent changes.

This kernel includes the two fixes you made.
"[PATCH] Fix RPC client warning in 2.5.58..."
and
"[PATCH] Fix NFS root mount handling"

I havn't seen any nfs/rpc related changes since these patches.

This is what I get when trying to start the nfs-server
(/etc/init.d/nfs-kernel-server in debian):

Installing knfsd (copyright (C) 1996 okir@monad.swb.de).
RPC: Couldn't create pipefs entry /portmap/clntcfac0540
RPC: Couldn't create pipefs entry /portmap/clntcfac0540
RPC: Couldn't create pipefs entry /portmap/clntcfac0540

I've mounted the rpc_pipefs filesystem and the directory
portmap/clntcfac0540 is created. It's empty but created.
It gets created with 500 as permissions.

the directories at the root of the rpc_pipefs filesystem get created
correctly with the permissions that your patch changed but not the
entries in these directories.

portmap does run as user daemon on this system.

I did check to make sure your patches were included and they were.

Output from rpcinfo:
# rpcinfo -p localhost

kernel compiled with gcc 3.2.2 if that matters.

Looking forward to suggestions/patches to test :)
