ReiserFS has unique inode numbers, but they aren't enough to actually find
the inode on disk. That requires the inode number, and another 32 bits of
information we call the packing locality. The packing locality starts as
the parent directory inode number, but does not change across renames.
So, we need to add a fh_to_dentry lookup operation for knfsd to use, and
perhaps a dentry_to_fh operation as well (but _fh_update in pre6 looks ok
for us).
