Subject: Linux regressions report  for mainline [2024-02-25]

Hi Linus, things look mostly normal from my point of view and a few
fixes for tracked issues are heading your way today or next week.
Nevertheless let me mention one issue where I fear that they might not
be fixed before the release:

* Decreased network outgoing speed due to irq sharing that started with
f977f4c9301c8a ("xhci: add handler for only one interrupt line"); the
report is already 22 days old and the discussion is slowly progressing
with no fix in sight (tglx was only brought in recently). Will prod
tomorrow, maybe that will help.

https://lore.kernel.org/lkml/4f34b6a8-4415-6ea4-8090-262847d606c6@linux.intel.com/

Johan Hovold also deals with multiple issues affecting Lenovo ThinkPad
X13s, but he send out patch series to fix some or all of those[1], so
with a bit of luck those issues will soon be fixed as well.

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

Currently I'm aware of 8 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@...ts.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/
