函数名称:map_find_next_zero_area_off - find a contiguous aligned zero area*@map: The address to base the search on*@size: The bitmap size in bits*@start: The bitnumber to start searching at*@nr: The number of zeroed bits we're looking for*@align_mask: Alignment
函数原型:unsigned long bitmap_find_next_zero_area_off(unsigned long *map, unsigned long size, unsigned long start, unsigned int nr, unsigned long align_mask, unsigned long align_offset)
返回类型:unsigned long
参数:
类型 | 参数 | 名称 |
---|---|---|
