Even for userland tasks, try_to_freeze() can currently be anywhere in the kernel. The frequently used ones are few but there are some odd ones out, and, again, there's nothing enforcing any structure on try_to_freeze() usage. The other thing is that we may do quite a bit during exiting including allocating memory. Are those safe for system PM? Rafael, what exactly are the rules for PM? What shouldn't change?
