This is v2 of my kernel memory tracking patchset for memcg. Lots of changes based on feedback from Glauber and Kamezawa. In particular, I changed it to be opt-in instead of opt-out: In order for a slab type to be tracked, it has to be marked with SLAB_MEMCG_ACCT at kmem_cache_create() time. Currently, only dentries and kmalloc are tracked. Planned for v3: - Slub support. - Using a static_branch to remove overhead when no cgroups have been created. - Getting rid of kmem_cache_get_ref/drop_ref pair in kmem_cache_free. Detailed change list from v1 (http://marc.info/?l=linux-mm&m=133038361014525): - Fixed misspelling in documentation. - Added flags field to struct mem_cgroup. - Moved independent_kmem_limit into flags. - Renamed kmem_bytes to kmem. - Divided consume_stock changes into two changes. - Fixed crash at boot when not every commit is applied. - Moved the new fields in kmem_cache into their own struct. - Got rid of SLAB_MEMCG slab flag. - Dropped accounting to root. - Added css_id into memcg slab name. - Changed memcg cache creation to always be deferred to workqueue. - Replaced bypass_bytes with overcharging the cgroup. - Got rid of #ifdef CONFIG_SLAB from memcontrol.c. - Got rid of __GFP_NOACCOUNT, changing to an opt-in model. - Remove kmem limit when turning off independent limit. - Moved the accounting of kmalloc to its own patch. - Removed useless parameters from memcg_create_kmem_cache(). - Get a ref to the css when enqueing cache for creation. - increased MAX_KMEM_CACHE_TYPES to 400.
