I wonder, did you actually test your patches? I ask, because it seems
that all your patches are of the same mechanical variety (produced by
some sort of research project?), and if I look around a bit, I see
several mistakes and regressions noted on your other patches. And
recently, I see someone reporting a 5.4 kernel regression, which looks
a lot like it was caused by this patch:

https://bugzilla.kernel.org/show_bug.cgi?id=207703#c1

I'll propose a revert, if there's no evidence this was actually tested
or otherwise confirmed to fix a real bug.
