    rcu: Simplify rcu_pending()/rcu_check_callbacks() API · a157229c
    Paul E. McKenney authored
    All calls from outside RCU are of the form:
    
    	if (rcu_pending(cpu))
    		rcu_check_callbacks(cpu, user);
    
    This is silly, instead we put a call to rcu_pending() in
    rcu_check_callbacks(), and then make the outside calls be to
    rcu_check_callbacks().  This cuts down on the code a bit and
    also gives the compiler a better chance of optimizing.
