Gmane
From: Glauber Costa <glommer-bzQdu9zFT3WakBO8gow8eQ <at> public.gmane.org>
Subject: [PATCH v5 00/18] slab accounting for memcg
Newsgroups: gmane.linux.kernel
Date: Friday 19th October 2012 14:20:24 UTC (over 3 years ago)
Note: This is basically the same as v4. During this week, I made some
changes
to this series in advance based on the feedback I had in the kmemcg-stack
last submission. Although the last series was not yet extensively reviewed,
I opted for sending this out so you guys have the most up2date code to
review.
So please review this one instead.

This is a followup to the previous kmem series. I divided them logically
so it gets easier for reviewers. But I believe they are ready to be merged
together (although we can do a two-pass merge if people would prefer)

Throwaway git tree found at:

	git://git.kernel.org/pub/scm/linux/kernel/git/glommer/memcg.git
kmemcg-slab

v5:
* code reorganization, name changes, etc.
v4:
* no more messing with the cache name after destruction: aggregated figures
  are shown in /proc/slabinfo.
* memory.kmem.slabinfo file with memcg-specific cache information during
its
  lifespan.
* full slub attribute propagation.
* reusing the standard workqueue mechanism.
* cache-side indexing, instead of memcg-side indexing. The memcg css_id
serves
  as an index, and we don't need extra indexes for that.
* struct memcg_cache_params no longer bundled in struct kmem_cache: We now
will
  have only a pointer in the struct, allowing memory consumption when
disable to
  fall down ever further.

Patches need to be adjusted to cope with those changes, but other than
that,
look the same - just a lot simpler.

I also put quite some effort to overcome my writing disability and get some
decent changelogs in place.

For a detailed explanation about this whole effort, please refer to my
previous
post (https://lkml.org/lkml/2012/10/8/119)

Glauber Costa (18):
  move slabinfo processing to slab_common.c
  move print_slabinfo_header to slab_common.c
  sl[au]b: process slabinfo_show in common code
  slab: don't preemptively remove element from list in cache destroy
  slab/slub: struct memcg_params
  consider a memcg parameter in kmem_create_cache
  Allocate memory for memcg caches whenever a new memcg appears
  memcg: infrastructure to match an allocation to the right cache
  memcg: skip memcg kmem allocations in specified code regions
  sl[au]b: always get the cache from its page in kfree
  sl[au]b: Allocate objects from memcg cache
  memcg: destroy memcg caches
  memcg/sl[au]b Track all the memcg children of a kmem_cache.
  memcg/sl[au]b: shrink dead caches
  Aggregate memcg cache values in slabinfo
  slab: propagate tunables values
  slub: slub-specific propagation changes.
  Add slab-specific documentation about the kmem controller
