Since this is fully compatible to LKMM atomic operations, is there a
use case for C and Rust operating on the same atomic value? And then
you will need to specify the size, or odd things are likely to happen
if they disagree on size. With Atomic<T> can we easily say what type
the underlying implementation uses?
