Linux regressions report for mainline [2024-01-07]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus. I noticed a handful of regression reports coming in over the
festive days, but fixes for most of those found their way into mainline
in the past few days. So from here it looks like the -rc8 was definitely
a wise move.

In the end I'm down to three regressions now (as usual: there are likely
more, but I can't have my eyes everywhere).

One regression[1] seems to have stalled due to lack of activity from the
reporter. It's similar with another that came in ~10 days ago[2]. The
third[3] came in before Christmas with a simple patch to fix it, but
sadly that afaics was not reviewed.

Ciao, Thorsten

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.:
