I'll do and have a plan. But there are several ongoing projects as a) per lruvec lock b) page cgroup diet c) kmem accounting d) hugetlb accounting e) some fixes in cgroup f) more tweaks in vmscan.c g) writeback and dirty ratio. I think it will come after a) and b), at least. And it's better to have g) before kswapd-for-memcg. Thanks, -Kame
