Here is a patch series that is a result of the memcg discussions on LSF (memcg-aware global reclaim, global lru removal, struct page_cgroup reduction, soft limit implementation) and the recent feature discussions on linux-mm. The long-term idea is to have memcgs no longer bolted to the side of the mm code, but integrate it as much as possible such that there is a native understanding of containers, and that the traditional !memcg setup is just a singular group. This series is an approach in that direction. It is a rather early snapshot, WIP, barely tested etc., but I wanted to get your opinions before further pursuing it. It is also part of my counter-argument to the proposals of adding memcg-reclaim-related user interfaces at this point in time, so I wanted to push this out the door before things are merged into .40. The patches are quite big, I am still looking for things to factor and split out, sorry for this. Documentation is on its way as well ;) #1 and #2 are boring preparational work. #3 makes traditional reclaim in vmscan.c memcg-aware, which is a prerequisite for both removal of the global lru in #5 and the way I reimplemented soft limit reclaim in #6. The diffstat so far looks like this: include/linux/memcontrol.h | 84 +++-- include/linux/mm_inline.h | 15 +- include/linux/mmzone.h | 10 +- include/linux/page_cgroup.h | 35 -- include/linux/swap.h | 4 - mm/memcontrol.c | 860 +++++++++++++------------------------------ mm/page_alloc.c | 2 +- mm/page_cgroup.c | 39 +-- mm/swap.c | 20 +- mm/vmscan.c | 273 +++++++-------- 10 files changed, 452 insertions(+), 890 deletions(-) It is based on .39-rc7 because of the memcg churn in -mm, but I'll rebase it in the near future.
