Is some bot > decising this or a human? this is controlled by human, we try to connect with regzbot for the regression we found on mainline. So we add #regzbot after we confirm the issue is valid on mainline. BTW: 0day does testing on nearly all repos from developer to maintainers to next and mainline, thus part of them are bisected down to mainline. > > Because the thing is: the time I can spend on tracking regressions is > limited, hence I (at least for now) want to avoid spending any time on > regressions that likely only ever show up in CI testing. But if the got it, probably we need consider a few test suites (and kernel configruations) that is more "standard", such as kselftests. But this is hard, for example, we detects performance issue on micro benchmark, and it only shows one perspective to developer as it may not reflect the use scenario of developer (thus sometimes it is not reasonable/necessary to fix). > problem is something that is likely to be seen in the wild it's totally > okay for me if you get regzbot involved.

I saw one case that you tracked a report from kernel test robot (0day) [1], can i understand that for now, you will monitor some mailing list and track them when it worths? BTW: i want to consult that anyone (or CI) else send report to regzbot directly so far? [1] https://lore.kernel.org/lkml/6b12a0b4-2f6d-1c35-f2e2-a28022583c47@leemhuis.info/ > > Ciao, Thorsten
