It was my mistake before, but do we need to align with the one used in
test_getpagesize():

    static int test_getpagesize(void)
    {
            long x = getpagesize();
            int c;
    
            if (x < 0)
                    return x;

Use 'long' instead of 'size_t' to declare page_size?

Thanks,
Zhangjin
