Subject: Linux regressions report  for mainline [2023-07-16]

Hi Linus. Nothing much to report from by side; there are a few
regressions I'm aware off, but everything currently is business as usual.

The iwlwifi issue I mentioned last week was fixed (thx again Johannes).
Kees picked up and sent you one compile fix in todays pull. Maybe you
also might still get this one for build failure from the tip folks:
https://lore.kernel.org/all/20230629102051.42E8360467@lion.mk-sys.cz/

Problem was reported here:
https://lore.kernel.org/lkml/20230628115825.ahqejf5y4hgxhyqj@lion.mk-sys.cz/

Ciao, Thorsten

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

Currently I'm aware of 10 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/
