bitmap_remap

函数名称：map_remap - Apply map defined by a pair of bitmaps to another bitmap*@dst: remapped result*@src: subset to be remapped*@old: defines domain of map*@new: defines range of map*@nbits: number of bits in each of these bitmaps* Let @old and @new define a

函数原型：void bitmap_remap(unsigned long *dst, const unsigned long *src, const unsigned long *old, const unsigned long *new, unsigned int nbits)

返回类型：void

参数：

类型	参数	名称
unsigned long *	dst
const unsigned long *	src
const unsigned long *	old
const unsigned long *	new
unsigned int	nbits

如果dst恒等于src则返回

811

bitmap_zero(dst, nbits)

813

w等于bitmap_weight(new, nbits)

815

n等于map_pos_to_ord - find ordinal of set bit at given position in bitmap*@buf: pointer to a bitmap*@pos: a bit position in @buf (0 <= @pos < @nbits)*@nbits: number of valid bit positions in @buf* Map the bit at position @pos in @buf (of length @nbits) to the

817

如果n小于0或w恒等于0则set_bit - Atomically set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* This is a relaxed atomic operation (no implied memory barriers).* Note that @nr may be almost arbitrarily large; this function is not

819

否则set_bit - Atomically set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* This is a relaxed atomic operation (no implied memory barriers).* Note that @nr may be almost arbitrarily large; this function is not
