Thanks! In that case: #regzbot fix: fd3a8cff4d4a #regzbot ignore-activity [better late than never] 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 That page also explains what to do if mails like this annoy you.
