Thanks.

A trick used by recent series from Patrick say things like "this is
based on X, with Y and Z merged".  This patch could have done the
same way.  It of course makes two topics entangled and one takes the
other hostage, so we need to carefully judge if such a dependency is
worth it.  So far, I found Patrick's judgement on the choice of
dependencies quite solid (essentially, Y and Z must be cooked enough
at least for 'next', and can reasonably be expected to graduate while
we iterate on the new topic that is being built).

Thanks.
