   I have no plans to do it -- I'm not even sure I want to touch any
   rename operation :-)

Heh, OK!  I guess dh or I will take care of that when we do next do
some namei or rename rototilling.  It will just let us get rid of an
extraneous lock/unlock cycle when looking up each child in rename.
(The other callers of relookup can just do a vn_lock right afterward.)
