函数名称：bitmap_equal

函数原型：static inline int bitmap_equal(const unsigned long *src1, const unsigned long *src2, unsigned int nbits)

返回类型：int

参数：

类型参数名称
const unsigned long *src1
const unsigned long *src2
unsigned intnbits
326  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:非src1按位异或src2的值按位与BITMAP_LAST_WORD_MASK(nbits)的值
328  如果__builtin_constant_p(nbits & BITMAP_MEM_MASK)且IS_ALIGNED(nbits, BITMAP_MEM_ALIGNMENT)则返回:非memcmp(src1, src2, nbits / 8)
331  返回:__bitmap_equal(src1, src2, nbits)
