Please update the title to

 rust: rename `AlwaysRefCounted` to `RefCounted`

No period in the summary line.

With that, you can add my review tag.

Reviewed-by: Andreas Hindborg <a.hindborg@kernel.org>

Since this patch touches so many moving parts of the rust tree, it is
going to be a cat and mouse game regarding rebasing this thing. It also
touches a lot if peoples code. I am not sure how something like this
would merge. Do we need ACK from everyone @Miguel?

Best regards,
Andreas Hindborg
