Probably not much, if we do it right. All we need to do is add a bit of
state logic in namei itself which, if we started with root, adds the
prefix once, does the lookup, and if it fails, try from /.

The only question would be how best to get the prefix info into namei. I
don't have source with me, so I don't know if we have the process context
around when either we set up the namei structure (NDINIT()) or not.

Take care,
