302 注意，这是一个两步的过程， region_add()和 region_abort()在事先调用 region_chg()后保证
303 成功。 region_chg()负责预先分配任何必要的数据结构以确保后续操作（特别是 region_add()）的
306 如上所述，region_chg()确定该范围内当前没有在映射中表示的页面的数量。region_add()返回添加
307 到映射中的范围内的页数。在大多数情况下， region_add() 的返回值与 region_chg() 的返回值相
308 同。然而，在共享映射的情况下，有可能在调用 region_chg() 和 region_add() 之间对预留映射进
353 这将调用 region_add()，用于指定的页面。与region_chg和region_add的情况一样，该函数应在
