You've misunderstood Greg. He's saying (effectively) "No fs bindings without a filesystem to use them". And Al, myself and others are saying "Your filesystem interfaces are wrong because they're not usable for real filesystems". And you're saying "But I'm not allowed to change them". And that's not true. Change them to be laid out how a real filesystem would need them to be. Or argue that your current interfaces are the right ones (they aren't).
