Jens, quick question: what's the plan forward here and who will realize what you outlined? I'm asking, as afaics nothing happened for a week (hope I didn't miss anything!). Sure, it's not a regression from the last cycle or so, so it's not that urgent. But hch's "It is not a regression at all" last week made me worry that this in the end might not be solved unless somebody has it on the todo list. Normally I would have CCed Linus at that point anyway to get his stance, but from your statements it sounds like this is unnecessary here. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
