Linux regressions report for mainline [2023-10-08]
From: Regzbot (on behalf of Thorsten Leemhuis)

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@xxxxxxxxxxxxxxxxxxxxxxx/
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

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.:
