Guilty as charged. Testing was on scarthgap. I currently does not have a
working test setup for master.

I guess I will have to wait with this until I can do proper testing
then.

I will resend this patch against scarthgap though, as it is valid and
tested there.

For master and styhead, I need to change to check
FILESYSTEM_PERMS_TABLES instead.
