rcu: shrink rcutiny by making synchronize_rcu_bh() be inline
Because synchronize_rcu_bh() is identical to synchronize_sched(), make the former a static inline invoking the latter, saving the overhead of an EXPORT_SYMBOL_GPL() and the duplicate code. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
