参数：

类型参数名称
struct mm_struct *mm
2525  easy_to_free等于0
2536  加自旋锁
2537  mm_slot等于get_mm_slot(mm)
2538  如果mm_slot且mm_slot不等于mm_slot则
2539  如果非rmap_list则

2542  easy_to_free等于1
2543  否则
2544  链表项移动到头部
2548  自旋锁解锁
2550  如果easy_to_free则
2551  free_mm_slot(mm_slot)
2552  lear_bit - Clears a bit in memory*@nr: Bit to clear*@addr: Address to start counting from* This is a relaxed atomic operation (no implied memory barriers).
2553  mmdrop(mm)
