函数名称：sched_rt_runtime_exceeded

函数原型：static int sched_rt_runtime_exceeded(struct rt_rq *rt_rq)

返回类型：int

参数：

类型参数名称
struct rt_rq *rt_rq
910  runtime等于sched_rt_runtime(rt_rq)
912  如果rt_throttled则返回:rt_rq_throttled(rt_rq)
915  如果runtime大于等于sched_rt_period(rt_rq)则返回:0
918  balance_runtime(rt_rq)
919  runtime等于sched_rt_runtime(rt_rq)
920  如果runtime恒等于Single value that denotes runtime == period, ie unlimited time.则返回:0
923  如果rt_time大于runtime则
924  rt_b等于sched_rt_bandwidth(rt_rq)
930  如果此条件成立可能性大(为编译器优化)(rt_runtime)则
931  rt_throttled等于1
932  printk_deferred_once("sched: RT throttling activated\n")
933  否则
939  rt_time等于0
942  如果rt_rq_throttled(rt_rq)则
943  sched_rt_rq_dequeue(rt_rq)
944  返回:1
948  返回:0
