Possibly fixed with these patches?

Thanks Alex,
it seems that Linus merged those patches (just today) for the next -rc release,
am I right?
If so, I'll do a quick test and let you know as soon as Ubuntu team will
release the next mainline kernel (usually just 1 or 2 days after -rc is out).

I confirm that the fix solves the bug on kernel 5.12.0-rc3 (at least on my test
system).
