I went back to the first patch in LKML for this series.
It seems your goal is that every include file should be standalone,
i.e it must include every definition it uses.

I disagree with this premise. It just makes things harder to maintain with
no real gain for any existing program.  What is the motivation for all this
useless churn? Is there some silly style rule that should be fixed instead?
