Linux regressions report for mainline [2022-12-11]

Linux regressions report for mainline [2022-12-11]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus! Below you'll find regzbot's report about regression from this
cycle the bot and I became aware of. Most of the issue I had on the list
last weeks were resolved, only a few problems that showed up in the past
few days remain. One of them is the bisected BPF issue you already are
aware of Jiri is looking into; the other two need more debugging and
afaics will only show up in special, not that common setups...

HTH, Ciao, Thorsten

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@lists.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.:
