I won't insist on keeping code that I haven't written. My only point is
that we use the code in set-top-boxes, where every byte is valuable. But
I suspect that there are numerous other places where we could safe
bytes... 8-)

Ok.

I don't get that, sorry. The backend modules have functional
dependencies and register/deregister upon loading/unloading. There is
never a call from the dvb-core to the backend modules. Do I really need
an owner field then?
