From: Dmitry Vyukov <dvyukov@xxxxxxxxxx>
Subject: kasan: support panic_on_warn
If user sets panic_on_warn, he wants kernel to panic if there is anything
barely wrong with the kernel. KASAN-detected errors are definitely not
less benign than an arbitrary kernel WARNING.
Panic after KASAN errors if panic_on_warn is set.
We use this for continuous fuzzing where we want kernel to stop and reboot
on any error.
