What I really love about this proposal is how it showcases the ongoing innovation in kernel security. We're not just patching individual vulnerabilities; we're rethinking core mechanisms to make the entire system more resilient.

For those of you who want to dig deeper, I highly recommend reading Kees's full patch set. And if you're feeling adventurous, why not try implementing this in your own kernel modules? There's no better way to understand security than by getting your hands dirty.
