Huh? You don't need that, a NFS server can run as pure user space, no
kernel work involved, it's just another network server. The only
possible issue is loopback mounting due to reentry issues or something
(there was a paper at Usenix 2001 IIRC about a toolkit for writing NFS
servers in C++, probably covers that). You just mount it with nfs
client, which does need to be in kernel but that's already in linux
