Don't bother with grsecurity.

Their approach has always been "we don't care if we break anything,
we'll just claim it's because we're extra secure".

The thing is a joke, and they are clowns. When they started talking
about people taking advantage of them, I stopped trying to be polite
about their bullshit.

Their patches are pure garbage.
