This is new nfs code (including nfsv4) imported from FreeBSD. It is
not even experimental yet - you don't want to be mucking with it.

The nfs code (both nfs and nfsd) that NetBSD currently uses is in
sys/nfs.


The following things are here:

  client/      - nfs client code, from sys/fs/nfsclient in freebsd
  server/      - nfsd server code, from sys/fs/nfsserver in freebsd
  nlm/         - kernel-side nfs lock manager, from sys/nlm in freebsd
  common/      - shared common code, from
                       * sys/fs/nfs in freebsd
                       * sys/nfs in freebsd
  files.newnfs - config goo
  nfs2netbsd.sh - script for preparing a cvs import from a freebsd tree

The FreeBSD shared common code contained two (different) nfsproto.h
and xdr_subs.h files. This is how they've been imported:

  sys/fs/nfs/nfsproto.h        ->      common/nfsproto.h
  sys/fs/nfs/xdr_subs.h        ->      common/xdr_subs.h
  sys/nfs/nfsproto.h           ->      common/oldnfsproto.h
  sys/nfs/xdr_subs.h           ->      common/old_xdr_subs.h
