Hi!

I see the other 6 patches from this series are in -next, but the
refcount_t implementation is still missing. What's needed to land this
in -next? It's blocking sending the atomic_t -> refcount_t patches,
which will likely all go through various maintainers, so we need to
have refcount_t first. :)

Thanks!
