While I don't know if is the first time this has happened, it's good to acknowledge this given all the crazy, odd, and incorrect press about Rust in Linux these days.

A new in-kernel api just landed in linux-next from my tree and should hopefully show up in 6.14 to make some kinds of drivers easier to write, that has a rust binding added at the exact same time:

Many thanks to Lyude and Danilo and many other Rust kernel developers for the help in creating the binding and make the C side work well for both Rust and C code at the same time. The end result here for any C developer alone, is much better off for all of their help.
