Hi Dmitry,

I'm on holiday and ignored these emails.
kvartet is an acquaintance of mine, I have no idea who Kaia is.
I have little knowledge of their actions. They may be new to the
kernel community and may not understand the rules in reporting bugs

Maybe we should add some `WARNING` in Syzkaller docs, e.g.,
`how_to_report_bug.md`, to tell people to polish their reports before
sending them out.
Or maybe we should just suppress all the `task-hung` and `kcsan`
reports in Syzkaller by default, enable them manually if the user
knows what they are doing.
