Ok, probably I'm just being dense, but the "_" prefix tells me I probably
shouldn't use this function. The comment clearly tells me I shouldn't use
this function.
So, why is this exported? And if it is not/should not be exported, then
why is it not static?
(goes for other functions in this patch as well).
