Subject: [PATCH 0/6] mm: per-lruvec slab stats

Hi everyone,

Josef is working on a new approach to balancing slab caches and the
page cache. For this to work, he needs slab cache statistics on the
lruvec level. These patches implement that by adding infrastructure
that allows updating and reading generic VM stat items per lruvec,
then switches some existing VM accounting sites, including the slab
accounting ones, to this new cgroup-aware API.

I'll follow up with more patches on this, because there is actually
substantial simplification that can be done to the memory controller
when we replace private memcg accounting with making the existing VM
accounting sites cgroup-aware. But this is enough for Josef to base
his slab reclaim work on, so here goes.
