I guess that is caused by the same issue. It's looking like privcmd is failing the ioctl with EINVAL rather than ENOTTY or EOPNOTSUPP for some reason. I'll need to look at the older privcmd source.

There are a lot of failed tests for the same step on 4.9 branch as well. I guess that is caused by the same issue.
