SubjectRe: kernel panic: MAC Initialization failed. (3)
From
Date
F.Y.I. Nothing is wrong with that commit. That commit merely allows enabling TOMOYO and
one of SELinux/Smack/AppArmor at the same time for syzbot's kernel command line options.
This problem will be handled by a patch at
https://lore.kernel.org/linux-security-module/1551362770-8655-1-git-send-email-penguin-kernel@I-love.SAKURA.ne.jp/
and then updating syzbot to build kernels with this option enabled.

Well, it is wonderful that syzbot started bisecting. ;-)
