I dislike the idea of a single patch crossing multiple subsystems. Maybe you'll
find another maintainer accepting your change as a single patch, but I won't.

That doesn't mean that the patches would have to be committed into multiple trees.
That is for the subsystem maintainers to sort out, and a different issue.
