Subject: RE: [RFC][PATCH 7/7] kref: Implement using refcount_t

>Provide refcount_t, an atomic_t like primitive built just for refcounting.
>It provides overflow and underflow checks as well as saturation semantics such that when it overflows, we'll never attempt to free it again, ever.

Peter do you have the changes to the refcount_t interface compare to the version in this patch? 
We are now starting working on atomic_t --> refcount_t conversions and it would save a bit of work to have latest version from you that we can be based upon. 

Best Regards,
Elena.
