Thank you for the feedback. 

I must admit I'm not good at all at selecting good names, so I
definitelly will apply the above. I additionally still have to cover
the feedback from Jacob - switching the reference count to a kref - as
I've been diverted to other tasks.

I hope to be able to share a new revision of this patch next week.

Thanks,

Paolo
