The point is: You could have done this in Rust, but you wouldn't have been required to do so, so the exact same logic bug could have emerged. Maybe it would be more Rust-like to write the code like that, but it would have also been possible to write the code like that in C - and since we're talking about the kernel here, even if this code was written in Rust a developer might have written it in the more C-like way for performance reasons.
