Rickard, your works are highly appreciated, but please think twice
before submitting patches: is it worth for the whole?

For example, in this case: the removals are static inline functions.
So there is no gain by removing this regarding the object size.  OTOH, 
they are obviously wrapper accessors, thus dropping blindly would
result in inconsistency.  That is, a reader may wonder later why some
are write only and some not.


thanks,

Takashi
