Rust Transitioning Kernel Code

Delete this >Rust >transitioning Sounds about right

A forum screenshot shows a code listing full of unsafe Rust functions, followed by a post claiming that the Linux kernel is now safe after merging Rust support and that the author will transition their codebase. Replies mock the claim by pointing out that the poster should delete it, while another sarcastically says that transitioning to Rust sounds about right. The joke targets overconfident claims about Rust making kernel code safe despite the visible abundance of unsafe code.
