Subject: [mm/kasan] 80a9201a59 BUG: kernel reboot-without-warning in
early-boot stage, last printk: Booting the kernel.
Hi Alexander,
FYI, we find an old bug that's still alive in linux-next. The attached
reproduce-* script may help debug the problem.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 80a9201a5965f4715d5c09790862e0df84ce0614

mm, kasan: switch SLUB to stackdepot, enable memory quarantine for SLUB
For KASAN builds:
- switch SLUB allocator to using stackdepot instead of storing the
allocation/deallocation stacks in the objects;
- change the freelist hook so that parts of the freelist can be put
into the quarantine.
