We do not doubt syzkaller is an incredible tool.

But netdev@ and lkml@ are mailing lists for humans to interact,
exchange ideas, send patches and review them.

To me, an issue that was reported to netdev by a real user is _way_ more important
than potential issues that a bot might have found doing crazy things.

We need to keep optimal S/N on mailing lists, so any bots trying to interact
with these lists must be very cautious and damn smart.

When I have time to spare and can work on syzbot reports, I am going to a web
page where I can see them and select the ones it makes sense to fix.
I hate having to set up email filters.
