That's true, on the other hand I have indeed a concerns with this patch:
this series is not bisectable at all, because all the new code is dead
until the very last patch. Uses of the new feature should come _after_
the implementation.

I don't have any big problem with what Liran pointed out (and I can live
with the unused static functions that would warn with -Wunused, too),
but the above should be fixed in v5, basically by moving patches 12-15
at the beginning of the series.
