Don't forget that for the case of NFS at least, you have to be able to
locate a file anywhere in the dentry tree from scratch after a server
reboot (All hail the god of stateless models). An fh_to_dentry() model
would need to do this too in an as efficient manner as possible.

I believe Neil has been working on a proposal for this within the
knfsd project, so I've Cced him in case he was unaware of this thread.
