Funny enough, it works perfectly. Generally as a test I boot the
kernel in a VM and let it fuzz with trinity for a bit, doing that with
the code above worked flawlessly.
While it works, it's obviously wrong. Why does it work though? Usually
there's a list op happening pretty soon after that which brings the
list into proper state.
I've been playing with a patch that adds a magic value into list_head
if CONFIG_DEBUG_LIST is set, and checks that magic in the list debug
code in lib/list_debug.c.
Does it sound like something useful? If so I'll send that patch out.
