When you do so, could you please include a proper "Link:" tag pointing to all reports of the regression, as explained in the Linux kernels documentation (see 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'). E.g. in this case: Link: https://bugzilla.kernel.org/show_bug.cgi?id=215696 Link: https://lore.kernel.org/lkml/CAE4VaGDZr_4wzRn2___eDYRtmdPaGGJdzu_LCSkJYuY9BEO3cw@mail.gmail.com/ This concept is not new (Linus and quite a few other developers use them like this for a long time), I just recently improved those documents to clarify things, as my regression tracking efforts rely on this (and there might be other people and software out there that does) -- that's why it's making my work a lot harder if such tags are missing. :-/ Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. > [...]
