        <pre>The final improvement we are likely to make for the time being is

commit 2850748ef8763ab46958e43a4d1c445f29eeb37d

    drm/i915: Pull i915_vma_pin under the vm->mutex

which removes the global struct_mutex from inside the shrinker -- so this pair
of benchmarks that appeared to be kicking kswapd should be hitting the mutex
far less often and so removing contention from the gfx workload.</pre>
