This is crap.  First of all, the logics is already overcomplicated.
_Then_ we have a problem of populating dcache for intermediates.

Besides, that's not what that thing is for - it's to allow local
caching (which we do) with revalidation of several components
at once.  _After_ VFS has decided that nothing interesting is in
the part of path it has cached.  Then the protocol allows to do
bulk Walk, verifying that all cached intermediates still match
the reality, all in one roundtrip.
