The next patch in this series uses it. I'm just splitting it up into a
separate patch so that it's digestible and I can provide more details
in the commit text.

Couple of options:
1. Drop the static in this patch and add it back when it's used in patch 18/18.
2. Drop the commit text and squash this with 18/18 if you think the
function documentation is clear enough and it won't make patch 18/18
too hard to review.

Please let me know which one you'd prefer or if you have other
options. I don't have a strong opinion on how the patches are split up
as long as it's easy for the reviewers and future folks who look at
git log to understand stuff.
