Okay, there are 151 bugs that syzbot saw on the mainline Linux kernel in the
last 7 days (90.1% with reproducers).  Of those, 59 were reported over 3 months
ago (89.8% with reproducers).  Of those, 12 were reported over a year ago (83.3%
with reproducers).

No opinion on whether those are small/medium/large numbers, in case it would
hurt someone's feelings.

These numbers do *not* include bugs that are still valid but weren't seen on
mainline in last 7 days, e.g.:

- Bugs that are seen only rarely, so by chance weren't seen in last 7 days.
- Bugs only in linux-next and/or subsystem branches.
- Bugs that were seen in mainline more than 7 days ago, and then only on
  linux-next or subsystem branch in last 7 days.
- Bugs that stopped being seen due to a change in syzkaller.
- Bugs that stopped being seen due to a change in kernel config.
- Bugs that stopped being seen due to other environment changes such as kernel
  command line parameters.
- Bugs that stopped being seen due to a kernel change that hid the bug but
  didn't actually fix it, i.e. still reachable in other ways.
