We can contrast this to what Regular Control Flow code needs
And then, find behaviours to block

Fuzzing the OpenBSD Kernel

Fuzzing the OpenBSD kernel using the syzkaller kernel fuzzer.
kcov(4)
A driver for tracking kernel code coverage.
Enabled on a per thread basis.
The kernel program counter is tracked during syscalls made by the same thread.
Not a strict requirement for syzkaller but improves its ability to generate interesting programs.
