Linux regressions report for mainline [2023-06-04]

Linux regressions report for mainline [2023-06-04]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus. Nothing much to report for mainline, all business as usual. I
had hoped Mauro would sent a pull with the media fixes, as they would
contain one fix[1] for a bug that at least two people hit, but I guess
it can wait another week.

Ohh, and in case you care: the Logitech HID bug[3] from the 6.3 cycle
was not really fixed[4] by commit 6199d23c91c or we dealt with two
problems all the time (I guess it's the latter). But that will take a
few days to sort out.

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

Currently I'm aware of 9 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.

All regressions marked '[ *NEW* ]' were added since the previous 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/

We opted to use a different approach for the same bug [1]: 
14b4bd01f8e5 ("media: verisilicon: Additional fix for the crash when opening the driver")

[1] https://lore.kernel.org/linux-media/e674cfcb-6b1b-8052-7f29-e0e97bdda3be@xs4all.nl/T/

Patch is already at linux-next. I'm sending the pull request in
a few, together with other fixes.

I was planning to send this earlier, but I got sick and had to take
some days off to recover my health.

Regards,
Mauro
