Subject: Linux regressions report  for mainline [2022-02-20]

Hi, Thorsten here, with a quick preface before the latest report from
regzbot. From my side things seem to look normal right now; in fact
quite a few mainline regression that I've been tracking got resolved in
the past few days (I removed two from the report that are fixed by
changes in the git tags Borislav and Dmitry asked you to pull this
weekend; guess you will merge them later today).

Sadly it seems I still don't get aware of quite a few regressions as
people don't CC the regressions mailing list. :-/ Well, that's life...

BTW, to reduce noise Regzbot now supports putting some regressions on
"back burner" and will not list them in the report, unless there was
recent activity; they are still visible in the web-ui.

I hope to work on better bugzilla.kernel.org integration soon, then
regzbot will show a proper "last activity date" when an issue is only
discussed in a ticket.

Ciao, Thorsten

Hi, this is regzbot, the Linux kernel regression tracking bot.

Currently I'm aware of 23 regressions in linux-mainline. Find the
current status below and the latest on the web:

Bye bye, hope to see you soon for the next report.

Thanks for your attention, have a nice day!

  Regzbot, your hard working Linux kernel regression tracking robot


P.S.: Wanna know more about regzbot or how to use it to track regressions
for your subsystem? Then check out the getting started guide or the
reference documentation:

https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md

The short version: if you see a regression report you want to see
tracked, just send a reply to the report where you Cc
regressions@...ts.linux.dev with a line like this:

#regzbot introduced: v5.13..v5.14-rc1

If you want to fix a tracked regression, just do what is expected
anyway: add a 'Link:' tag with the url to the report, e.g.:

Link: https://lore.kernel.org/all/30th.anniversary.repost@klaava.Helsinki.FI/
