Linux regressions report for mainline [2023-10-01]

From: Regzbot (on behalf of Thorsten Leemhuis)
Date: Sun Oct 01 2023 - 09:44:07 EST


Hi Linus. There is not much to report wrt to regressions introduced
during the current cycle; quite a few new reports showed up this week
(see below), but nothing to worry about afaics. And the 6.5-rc6
regression I mentioned in last weeks report is also soon history, as
Greg sent you the merge request with the fix today (see "[GIT PULL]
Char/Misc driver fix for 6.6-rc4").

Ciao, Thorsten

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

Currently I'm aware of 8 regressions in linux-mainline. Find the

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@xxxxxxxxxxxxxxx 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.:
