Subject: Linux regressions report  for mainline [2022-03-06]

Hi Linus, Thorsten here, with a quick preface before the latest report
from regzbot.

>From my side things seem to look normal right now; quite a few
regressions got fixed in the past few days. I (and thus regzbot) are
only aware of two regressions remaining that got introduced this cycle
(at least one of them pretty special); I didn't add those build problems
from Guenter to the tracking: he seems to look after those quite well
already (I need to talk to him if he want's me to track them, but I
didn't get around to do that).

Sadly I'm guess there are some regressions out there which I and regzbot
are not aware of. Hopefully more people will at least CC the regressions
mailing list (regressions@...ts.linux.dev) on regressions reports in the
future (and/or get regzbot involved themselves), as that ensures I'll
get aware of them.

Ciao, Thorsten

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

Currently I'm aware of 15 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/
