Yes, I know this. Alexander Viro changed the interface. I have chosen
not to change the code for now, since it should work anyway. I will
have to use lots of ugly #ifdef:s, and that's why it wasn't included
in 0.24. The code will change in the future, though.

Yes, it was part of the big changes that also included the rename
semantic change. That is, however, changed in arla 0.24.
