Hi, v3 for LKMM atomics in Rust, you can find the previous versions: 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 v2: * Drop the temporary RCU binding since they are already in mainline. * Fix a few "Ipml" typos in previous versions per feedback from Alice Ryhl. * Documentation improvement per feedback from Alice Ryhl. I'm hoping to at least get the first 8 patches (atomic operations on normal integer) in a good shape so that we can have them in v6.16. Thanks!
