Linux regressions report for mainline [2023-02-11]

From: Regzbot (on behalf of Thorsten Leemhuis)
Date: Sat Feb 11 2023 - 12:28:58 EST


Hi Linus. Below you'll find regzbot's report about regression from this
cycle me or someone else told the bot about. One day earlier than usual,
as I'm on the road tomorrow.

Let me quickly mention a few random things with available fixes:

* the fix for a SPI issue I already mentioned two weeks ago is still
sitting in next; the reporter complained about that today, as the "whole
test infrastructure crashes [due to that bug] preventing the normal
testing we normally do on mainline kernel".
https://lore.kernel.org/lkml/Y8U9vrwzHVAyBZHK@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=master&id=eede42c9459b58b71edc99303dad65216a655810
https://lore.kernel.org/lkml/Y%2BexzSwy1UJQCUKg@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/

* David already sent BTRFS updates this week, but right after that
merged a fix for a issue that affected quite a few people on 6.1 to his
tree. Not sure if he'll send it in for rc8, which might be better than
applying it next week right before the release. And it liekly would make
a few 6.1.y users happy if the fix might land in 6.1.y a week earlier, too:
https://lore.kernel.org/linux-btrfs/20230206184044.GD28288@xxxxxxxxxxxxx/
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=master&id=6afaed53cc9adde69d8a76ff5b4d740d5efbc54c

* A patch to fix a page corruption caused by racy check in __free_pages
emerged on Thursday. It's caused by a change merged for 5.10-rc1, but
Vlastimil nevertheless said "That's nasty enough to go into 6.2, IMHO".
Willy reviewed it, but Andrew didn't pick it up yet.
https://lore.kernel.org/lkml/BYAPR02MB448855960A9656EEA81141FC94D99@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/

And one other thing:

* Last week I mentioned a long and ongoing discussion about problems
with the NFS client where there was some disagreement if the issue
qualifies as regression, as it's an old problem with tmpfs that is more
likely to happen now. That discussion afaics faded out a few days ago
without a fix or a revert (which if I remember the discussion correctly
would be possible) in sight (unless I missed it):
https://lore.kernel.org/linux-nfs/9A4A5673-691D-47EC-BC44-C43BE7E50A48@xxxxxxxxxx/

There are still quite a few known issues from this cycle mentioned
below. Afaics none of them affect a lot of people; and with a bit of
luck one or two might still be fixed next week. I'm just a bit unhappy
that it takes so long to get "Black screen when amdgpu started during
6.2-rc1 boot with AMD IOMMU enabled" fixed, but well, there is quite a
bit discussion about it, so people tried.

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

Currently I'm aware of 10 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.:
