The gcs-locking test case currently only covers locking combinations of the various flags that can be set for GCS (enable, write and push) where enable is included in the locked bits. Since it is valid to only lock a combination of write and push while leaving enable user controllable we should also cover those cases, add coverage for them. The new cases pass as expected.
