bitmap_fold

函数名称：map_fold - fold larger bitmap into smaller, modulo specified size*@dst: resulting smaller bitmap*@orig: original larger bitmap*@sz: specified size*@nbits: number of bits in each of these bitmaps

函数原型：void bitmap_fold(unsigned long *dst, const unsigned long *orig, unsigned int sz, unsigned int nbits)

返回类型：void

参数：

类型	参数	名称
unsigned long *	dst
const unsigned long *	orig
unsigned int	sz
unsigned int	nbits

如果dst恒等于orig则返回

bitmap_zero(dst, nbits)

1015

for_each_set_bit(oldbit, orig, nbits)
