Hi all, This is the v8 of LKMM atomics in Rust, you can find the previous versions at: v7: https://lore.kernel.org/rust-for-linux/[email protected]/ v6: https://lore.kernel.org/rust-for-linux/[email protected]/ v5: https://lore.kernel.org/rust-for-linux/[email protected]/ v4: https://lore.kernel.org/rust-for-linux/[email protected]/ v3: https://lore.kernel.org/rust-for-linux/[email protected]/ v2: https://lore.kernel.org/rust-for-linux/[email protected]/ v1: https://lore.kernel.org/rust-for-linux/[email protected]/ wip: https://lore.kernel.org/rust-for-linux/[email protected]/ Changes since v7: - A lot of trait renaming per the suggestion of Benno. - Add new internal type `AtomicRepr<T>` to make Atomc*Ops function safe. - Rename atomic/ops.rs => atomic/internal.rs per the suggestion of Benno. - Move `Atomic<T>`, `AtomicType` and `AtomicAdd` into atomic.rs. - Remove atomic/generic.rs and move `impl AtomciType for {i,u}{32, 64, size}` blocks and the tests into a new atomic/predefine.rs file. - Make `internal` not public, except that `AtomicImpl` is public. - Other minor documentation improvememt.
