SubjectLinux regressions report for mainline [2022-05-09] (was: Linux 5.18-rc6)
Date
Hi Linus! Here's a quick compilation of open reports about regressions in
5.18-rc that I'm currently aware of; most of the reports are quite
recent and there afaics is nothing that looks particularly worrisome.

Sorry, I didn't get around to sent any reports in that past few weeks, I
simply didn't find enough time to get on top of things to compile a
meaningful report. But I nevertheless had an eye on things an poked some
developers when it seemed there wasn't any progress.

On reason why I was short on time: the number of tracked open
regressions increased a bit over the past few weeks. Most of them are
found in older cycles. Listing them all here would make the report quite
long and hard to read -- and people then might stop reading them, which
I'd like to avoid. That's why I stopped including all and only focused
on the ones in the current cycle. Is that okay for you? Or would you
prefer to have at least those from the previous cycle listed as well? Or
at least all that were bisected? Or should I split things up over
multiple reports? Or is having the others on the website enough for
everyone?

Ciao, Thorsten

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

Currently I'm aware of 5 regressions in linux-mainline that
where introduced this cycle. Find the current status below
and the latest on the web:

https://linux-regtracking.leemhuis.info/regzbot/mainline/

Regressions from previous cycles are listed there as well.

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.:

Link: https://lore.kernel.org/all/30th.anniversary.repost@klaava.Helsinki.FI/
