I did go poke, it is listed off the reports too. But it'd be really
handy if you could do this on the web page. When I see a report like
that that's not for me, I just archive it. And like any chatter with
syzbot, I have to look up what to reply to it every time. It'd be a lot
easy if I could just click on that page to either mark as invalid
(providing the info there) or move it to another subsystem.
