No, there are a handful that we know don't pass.  When I run on NFS v4.1, I get:

        Failures: generic/035 generic/071 generic/128 generic/294 generic/306 generic/309 generic/310 generic/313 generic/314 generic/315 generic/316 generic/319 generic/337 generic/360 generic/375
        Failed 15 of 92 tests

Thanks,
Anna
