Still catching up but the patch itself is a kind of disclosure, and this one is a tough one to keep under wraps as it will so obviously degrade performance, making people look wtf. But broader lesson speeding up the patch rate is important too.
yeah but KPTI... Kinda screams the problem? OTOH, one can argue that Register should have held back *and* that everyone should have acted like disclosure of sorts had happened (though presumably they were rushing? one hopes?)
