uretprobes: Return probe exit, invoke handlers Uretprobe handlers are invoked when the trampoline is hit, on completion the trampoline is replaced with the saved return address and the uretprobe instance deleted. TODO: handle_trampoline() assumes that ->return_instances is always valid. We should teach it to handle longjmp() which can invalidate the pending return_instance's. This is nontrivial, we will try to do this in a separate series.
