It's where the discussion started and it's still in the subject of the thread ! You noted that with distro kernels, hiding kallsyms is useless since uname -r reveals what kernel to download to get them anyway. Which is true !
Reason why it would be more efficient to find how we could randomize those pointers at runtime.

That's also what I was about to say. Let's agree we disagree and have a nice sunday afternoon. We can bring the discussion back around a beer if you happen to pass by Paris :-)
