  Hm, I don't know about knfsd people but I am thinking about something like
fh_to_dentry and dentry_to_fh pair. The main idea ( suggested by Al ) is
to allow dentry tree to grow in two different directions: from root to leaves
and from leaves to root. The main trick will be to select right splicer and
to allow quick grow for upside direction. It seems, that this will satisfy
NFS as is, and will provide a way for unique "external" representation of
the dentry tree.
