Hi Steven,
No personal criticism meant. I guess this is an inevitable consequence of the current kernel development process and tooling. Reports and patches get lots on a regular basis. In some subsystems we don't hear from maintainers at all. That's one of the things we wanted to solve with the syzbot dashboard: no thing get lost ever: https://syzkaller.appspot.com/#upstream But the other side of the medal is that bug report statues need to be maintained.
