--- Comment #11 from Chris Wilson <chris at chris-wilson.co.uk> ---
The before- tests are meant to fail. Userspace is leaving the caches polluted
and not performing any domain changes (no clflushes) prior to access. Their
only purpose was to prove that we cannot apply this optimisation in the kernel
and userspace must also be wary of not falling into the same trap.
