Sorry for making uninformed guesses, but if there are already special nodes 
(whiteout), why not extending them to some more general format - specifying a 
(source, destination) pair at the topmost level?
- A delete is a (source, NULL) pair
- A rename is a (source, destination) pair, which causes lookups on source to
  use the string destination in the lower branches.


Would that work?
