函数名称：__mem_cgroup_insert_exceeded

函数原型：static void __mem_cgroup_insert_exceeded(struct mem_cgroup_per_node *mz, struct mem_cgroup_tree_per_node *mctz, unsigned long new_usage_in_excess)

返回类型：void

参数：

类型参数名称
struct mem_cgroup_per_node *mz
struct mem_cgroup_tree_per_node *mctz
unsigned longnew_usage_in_excess
518  p等于rb_node
519  struct rb_node * parent = NULL
521  bool rightmost = true
523  如果he soft limit is exceeded则返回
526  Set to the value by which 等于new_usage_in_excess
527  如果非Set to the value by which 则返回
529  当p循环
530  parent等于p
531  mz_node等于rb_entry(parent, structmem_cgroup_per_node, tree_node)
533  如果Set to the value by which 小于Set to the value by which 则
534  p等于rb_left
535  rightmost = false
542  否则如果Set to the value by which 大于等于Set to the value by which 则p等于rb_right
546  如果rightmost则rb_rightmost等于RB tree node
549  rb_link_node( & RB tree node , parent, p)
550  rb_insert_color( & RB tree node , & rb_root)
551  he soft limit is exceeded = true
