Hi,
Could you please Cc the stakeholders for each issue (especially when
there is a reproducer)? Not everybody reads every single message that
shows up in the kernel.
cheers,

One nit - p9 is not really net.
Thanks again for restarting the reports!

At least it's not reflected in MAINTAINERS:
$ ./scripts/get_maintainer.pl --nom --nor ./net/9p/
v9fs@lists.linux.dev (open list:9P FILE SYSTEM)
netdev@vger.kernel.org (open list:NETWORKING [GENERAL])
linux-kernel@vger.kernel.org (open list)
Maybe it could be worth it to add "X: net/9p/" to "NETWORKING [GENERAL]"?
Syzbot would then eventually also pick up the change.

Hi Jamal,
This sounds interesting, thanks for the suggestion!
It would be a lot of emails though, so maybe we could randomly pick a
few of them each time.
I've filed https://github.com/google/syzkaller/issues/4369
