参数：

类型参数名称
struct sched_rt_entity *rt_se
unsigned intflags
1233  rt_rq等于rt_rq_of_se(rt_se)
1234  array等于active
1235  group_rq等于group_rt_rq(rt_se)
1236  queue等于queue加rt_se_prio(rt_se)
1244  如果group_rq且rt_rq_throttled(group_rq)或非rt_nr_running的值则
1245  如果on_list则__delist_rt_entity(rt_se, array)
1247  返回
1250  如果Change rt_se->run_list location unless SAVE && !MOVE* assumes ENQUEUE/DEQUEUE flags match则
1251  WARN_ON_ONCE(on_list)
1252  如果flags按位与ENQUEUE_HEAD则添加链表项
1254  否则添加链表项
1257  __set_bit - Set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* Unlike set_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation* succeeds.
1258  on_list等于1
1260  on_rq等于1
