Linux regressions report for mainline [2022-11-27]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus! Below is a slightly edited report from regzbot listing all
regression from this cycle that the bot and I are currently aware of.

One net regression is brand new and a fix already was posted. The
arm64/qcom one reently was discussed. The arm64/drm one looks stalled
and is waiting for feedback from the reporter afaics; I already send
an inquiry, but that didn't help.

HTH, Ciao, Thorsten

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

Currently I'm aware of 3 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@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.:
