类型参数名称
struct cfs_rq *cfs_rq
struct sched_entity *se
566  link等于rb_node
567  struct rb_node * parent = NULL
569  bool leftmost = true
574  当link循环
575  parent等于link
576  entry等于rb_entry(parent, structsched_entity, run_node)
581  如果entity_before(se, entry)则
582  link等于rb_left
583  否则
584  link等于rb_right
585  leftmost = false
589  rb_link_node( & run_node, parent, link)
