However older kernels returned a smaller number (or even -1, for the initial code), and the kselftest documentation states that older kernels should still be supported. Relax the test for the return value, to just not accept 0, which was never a value returned by this syscall (the initial ABI version was 1). This fixes kselftests runs on older kernels like on my Ubuntu 20.04 system.
