I'm a bit unsure what to do with this and consider asking Greg for advice, as he applied the patch. On one hand it's *IMHO* clearly a regression (but for the record, some people involved in the discussion claim it's not). OTOH the culprit was applied more than a year ago now, so reverting it might cause more trouble than it's worth at this point, as that could lead to regressions for other users. 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. #regzbot poke
