Subject: Linux regressions report  for mainline [2023-10-08]

Hi Linus. There is not much to report wrt to regressions introduced
during the current cycle: there are a few, put people are working on
fixing them.

Except maybe one; but I'll likely drop that from the list of tracked
issues anyway, unless you object:
https://lore.kernel.org/all/eab8e74b-61e0-4ef4-bfb3-751047d879bc@green-communications.fr/

As far as I understand things the cause is 3ec5ac12ac8a4e ("wifi: mt76:
mt7915: remove VHT160 capability on MT7915") [v6.6-rc1] which removed a
erroneously added feature flag (introduced in c2f73eacee3bf1 ("wifi:
mt76: mt7915: add back 160MHz channel width support for MT7915")
[v6.3-rc4]) which broke a user's hostap configuration. But I guess there
is nothing much we can do here, as the hardware doesn't support that
feature. See above link for details.

Ciao, Thorsten

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@...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/
