    TWIMC: this mail is primarily send for documentation purposes and for
    regzbot, my Linux kernel regression tracking bot. These mails usually
    contain '#forregzbot' in the subject, to make them easy to spot and filter.

    Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

    P.S.: As the Linux kernel's regression tracker I deal with a lot of
    reports and sometimes miss something important when writing mails like
    this. If that's the case here, don't hesitate to tell me in a public
    reply, it's in everyone's interest to set the public record straight.

    For the record: the fix was merged through a different branch and thus
    got a different commit id:
