Hm, you are right, I did not notice this other one somehow.
So, not to take any guesses, should I convert the other goto retry into
retry_deleg similar in style to what happens in rename and unlink, only
make retry)deleg label before call to the security_path_link?
After the call to the security_path_link?
Or would you prefer to just free old_path in both cases?
