Correct, this was my thinking too.
But for example, I did not check how far back UAPI loop.h was
provided, and whether users have it available at klibc build time. And
kind of wanted to show the bug with current loop.h, such that it's
available for cherrypicking & backports.
But indeed, either of the two patches fixes the identified problem.
One is minimal, and this one is slightly more invasive.
