Now that synchronize_rcu() waits for preempt-disable regions of code as well as RCU read-side critical sections, synchronize_sched() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com> Cc: Francois Romieu <romieu@fr.zoreil.com> Cc: "David S.
