The hits just keep on coming for me it seems. I had this fixed locally
and I'm not even sure how I ended up propagating this patch. It all
broke when I rebased the original patch series to split this fix out.

Even more unfortunate is this repo with the changes has long since been
corrupted to destruction. So I shall fix this for the forced throttling
series, and you can take it from there if you like it.

Thanks for catching this. Shame on me...
