bitmap_weight

函数名称：bitmap_weight

函数原型：static __always_inline int bitmap_weight(const unsigned long *src, unsigned int nbits)

返回类型：int

参数：

类型	参数	名称
const unsigned long *	src
unsigned int	nbits

390

如果The static inlines below do not handle constant nbits==0 correctly,* so make such users (should any ever turn up) call the out-of-line* versions.(nbits)则返回:hweight_long( * src & BITMAP_LAST_WORD_MASK(nbits))

392

返回:__bitmap_weight(src, nbits)
