Let's see if I can remember the candidates...

	rcu_is_cpu_idle() # reversed sense from the others
	rcu_is_ignored() # reversed sense from the others
	rcu_is_not_active() # reversed sense from the others
	rcu_is_watching_cpu()
	rcu_read_check()
	rcu_is_active()
	rcu_is_active_local()
	rcu_is_online()
	rcu_is_watching_task()
	rcu_is_watching_thread()
	rcu_is_watching_you()
	all_your_base_are_belong_to_rcu()
	rcu_is_active_loco()
	rcu_kilroy_was_here()

Maybe I should just lock them all in a room overnight and see which
are still alive in the morning.

							Thanx, Paul
