I'm wondering if we should ask Stephen to drop mm-vmstat-move-slab-statistics-from-zone-to-node-counters.patch mm-memcontrol-use-the-node-native-slab-memory-counters.patch mm-memcontrol-use-generic-mod_memcg_page_state-for-kmem-pages.patch mm-memcontrol-per-lruvec-stats-infrastructure.patch mm-memcontrol-account-slab-stats-per-lruvec.patch until that is sorted?
