If we fail on memcmp() here, the ret should be set to non-zero *explicitly*.
Otherwise, we have zero exit code since statx returns 0 on success.
I think that one can also be simplified like this:
ret = memcmp(&x1, &x2, sizeof(x1));
if (ret)
fprintf(stderr, "Miscompare between io_uring and statx\n");
return ret;
