Re: [PATCH v2] rbtree: fix the red root

Unfortunately, I could not trigger any of those here both in a bare-metal and
virtual machines. All I triggered were hung tasks and soft-lockup due to fork bomb.

The only other thing I can think of is to setup kdump to capture a vmcore when
either GPF or BUG() happens, and then share the vmcore somewhere, so I might
pork around to see where the memory corruption looks like.
