bitmap_pos_to

函数名称：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

函数原型：static int bitmap_pos_to_ord(const unsigned long *buf, unsigned int pos, unsigned int nbits)

返回类型：int

参数：

类型	参数	名称
const unsigned long *	buf
unsigned int	pos
unsigned int	nbits

735

如果pos大于等于nbits或非st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:负1

738

返回:__bitmap_weight(buf, pos)
