Hi Linus, from the regressions point of view it's business as usual and
nothing to worry about afaics.

There is a small fix for a fs/9p regression is sitting in a vfs.netfs
branch for 18 days now; I had expected that it would finally make it to
you this week, but that did not happen; will poke Al and Christian tomorrow:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=master&id=ca9ca1a5d5a980550db1001ea825f9fdfa550b83

There is also one regression from this cycle that looks somewhat
stalled, but Hans promised to look into it soon:

Ciao, Thorsten

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

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@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.:
