I really absolutely still detest this all. I don't see the point. The
naming is completely random (both "twist" and then options like
"TWIST_FOR_SYZKALLER_TESTING" that have no conceptual meaning.
I still don't understand why this small set of random options couldn't
just be kernel options that get set on the command line, and that have
independent and sane and explainable behavior? Why this odd mentality
of "syzkaller is special"?
I've complained about this whole thing before. I'm getting really fed
up with this whole concept of "magic crazy config options".
The kernel configuration phase is just about the _worst_ part of the
kernel, we shouldn't make these pointless things make it even worse.
