Linux regressions report for mainline [2022-09-04]

["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 aware of.

People are working on fixing most of those where the root cause it
known; for some a fix is not far away or even on your way already.
There is just one regression found by 0-day bot ("[sched] f3dd3f6745:
fxmark.ssd_ext4_no_jnl_DWSL_72_directio.works/sec -30.5% regression")
that didn't get a single reply; and one from 0-day ("d4252071b9:
fxmark.ssd_ext4_no_jnl_DWTL_54_directio.works/sec -26.5% regression")
where you replied, but nobody else.

HTH, Ciao, Thorsten

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

Currently I'm aware of 9 regressions in linux-mainline introduced
this cycle. 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@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.:
