Unless I misread the patch, this is the only caller of _setfns(), and
this helper is really trivial and probably deserves to be inline. But
this is very minor.

Personally I think these patches are nice. Not only this series adds
the new functionality, in my opinion it also cleanups and simplifies
the code.
