* rcu: Simplify rcu_pending()/rcu_check_callbacks() APIPaul E. McKenney2009-08-231-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Paul E.
