Linux regressions report for mainline [2022-03-20]

From: Regzbot (on behalf of Thorsten Leemhuis)
Date: Sun Mar 20 2022 - 12:27:05 EST


Hi Linus, Thorsten here, with a quick preface before the latest report
from regzbot.

>From my side things look normal right now. Regzbot is aware of three
(maybe just two) regressions in mainline:

* one in cifs that needs further tests
* one in hid/input where a patch exists, but needs polishing; and the
issue seems to affect only two Laptop models anyway
* one in DRM that might in fact be a problem already introduced in 5.11
(the report is not clear on this); the fix is in Linux-next
(27599aacbaef) for a few weeks already; for details see
https://bugzilla.kernel.org/show_bug.cgi?id!5678

Nothing else from my side.

Ciao, Thorsten

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

Currently I'm aware of 17 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.:

Link: https://lore.kernel.org/all/30th.anniversary.repost@xxxxxxxxxxxxxxxxxx/
