This whole thing needs to be reviewed and acked by the NFS community,
and quite frankly I'm inclined to NAK this. This is the second time
David tries to push this unwanted rewrite of totally unrelated code.

No problem on that. I just want it to build cleanly.

Rewrite? What?

It's example code of what NFS could export through this interface. I didn't
submit it to Linus with the rest of the patches as it's only an example; same
for the ext4 example. I've tried running it past you and other NFS people a
couple of times to try and elicit a response and wanted to try and ask you
about it at LSF:-(

Anyway, I've dropped it for now.
