Please explain a bit how this solves the problem. I'm sure it's
obvious to you, but this series is a complete mystery to me. Sure, I
could read the code and puzzle it all together, but since you already
know what it's for, it would be more efficient for us if you
explained.

Also, it feels like these three patches belong in a single patch, but
maybe it will be clearer what the purpose of each patch is once you've
explained it.
