["Regzbot (on behalf of Thorsten Leemhuis)" <regressions@leemhuis.info>]

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.

For two of those five regressions a patch was accepted by the
maintainer, but is not even yet in linux-next afaics.

HTH, 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@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.:
