[$] Using LKMM atomics in Rust

Rust, like C, has its own memory model describing how concurrent access to the
same data by multiple threads can behave.
The Linux kernel, however, has its own
ideas. The

Linux kernel memory model (LKMM) is subtly different from both the
standard C memory model and Rust's model.
At Kangrejos, Boqun Feng gave a presentation about the
need to reconcile the memory models used by Rust and the kernel,
including a few potential avenues for doing so. While
no consensus was reached, it is an area of active discussion.
