To be sure this issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot: #regzbot ^introduced f17dca0ab3f38b19c0f1b935f417f62d4a528723 #regzbot ignore-activity FYI: I removed everyone else and the other lists from the To or CC to avoid noise, as this mail is meaningless for them. Ciao, Thorsten, your Linux kernel regression tracker. P.S.: If you want to know more about regzbot, check out its web-interface, the getting start guide, and/or the references documentation: https://linux-regtracking.leemhuis.info/regzbot/ https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md But note, regzbot is doing its first field-testing now and thus still has some bugs. Adding this regression will help be to find them, hence feel free to ignore it and any errors in the web-ui.
