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.

Hi, this is your Linux kernel regression tracker. Top-posting for once,
to make this easily accessible to everyone.

As per recent general discussions with the 0-day folks, I'm dropping
below regression report from the list of tracked issues, as this report
didn't gain any traction. That for example can happen if the developers
considered the regression of no practical relevance, as they assume it
only materializes in micro-benchmarks, is due to a broken test case, or
some fluke – and then they often not even reply.

Not sure if that or something else is the reason why this particular
report didn't gain any traction, but I lack the bandwidth to follow-up
on each and every performace regression 0-day bot found and reported. At
the same time I don't want to keep these reports in the list of tracked
issues forever, as that creates noise and makes it harder to spot the
important issues in regzbot's reports and lists. That's why I hereby
remove it:

#regzbot invalid: 0-day report that didn't get traction; likely of no
relevance, not sure

Ciao, Thorsten
