ext4: optimize test_root()
The test_root() function could potentially loop forever due to
overflow issues. So rewrite test_root() to avoid this issue; as a
bonus, it is 38% faster when benchmarked via a test loop:
int main(int argc, char **argv)
{
int i;
for (i = 0; i < 1 << 24; i++) {
if (test_root(i, 7))
printf("%d\n", i);
}
}
