6022  batch等于zone_managed_pages(zone)除1024
6024  如果batch乘PAGE_SIZE大于1024乘1024则batch等于1024乘1024除PAGE_SIZE
6026  batch除等于4
6027  如果batch小于1则batch等于1
6040  batch等于unddown_pow_of_two - round the given value down to nearest power of two*@n: parameter* round the given value down to the nearest power of two* - the result is undefined when n == 0* - this can be used to initialise global variables from constant data(batch + batch / 2)减1
