Another possible "solution" works in the opposite direction, since the
folder rust/kernel/sync/atomic is quite stand-alone, we can export that
as a Rust crate (library), and third party code can support using LKMM
atomics instead of Rust own atomics ;-) Of course if the project is
supposed to work with Linux kernel.
