NFSv2 and v3 have a fixed format for readdir calls. There's bugger all
you can do to change this without making the resulting protocol
incompatible with NFS.

If you don't want Reiserfs to be NFS compatible, then fine, but I
personally don't want to see hacks to the NFS v2/v3 code that rely on
'hidden knowledge' of the filesystem on the server.
