The idea lying behind it is very simple - instead of pointing from kmem objects (kmem caches, non-slab kmem pages) directly to the memcg which they are charged against, we make them point to a proxy object, mem_cgroup_kmem_context, which, in turn, points to the memcg which it belongs to. As a result on memcg offline, it's enough to only re-parent the memcg's mem_cgroup_kmem_context. Note, reparented kmem contexts will hang around until there is at least one object accounted to them, but since they are small (especially comparing to struct mem_cgroup), it's no big deal. Reviews are appreciated. Thanks, Vladimir Davydov (8): memcg: add pointer from memcg_cache_params to owner cache memcg: keep all children of each root cache on a list slab: guarantee unique kmem cache naming slub: remove kmemcg id from create_unique_id memcg: rework non-slab kmem pages charge path memcg: introduce kmem context memcg: move some kmem definitions upper memcg: reparent kmem context on memcg offline include/linux/memcontrol.h | 88 ++++----- include/linux/mm_types.h | 6 + include/linux/slab.h | 17 +- mm/memcontrol.c | 468 +++++++++++++++++++++----------------------- mm/page_alloc.c | 22 ++- mm/slab.c | 40 ++-- mm/slab_common.c | 64 ++++-- mm/slub.c | 45 ++--- 8 files changed, 382 insertions(+), 368 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
