Hi, Thorsten here, the Linux kernel's regression tracker.
I see that v2[1] got a lot of ACKs, but is not even yet in next. And
it's a lot of patches, so maybe too much for backporting to stable
kernels. Which leads to the question: Will the regression this thread is
about (introduced in 5.19 afaics) ever be fixed in v6.1?
Normally/Ideally it should be.
Ciao, Thorsten
