Patch series "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1". This patchset puts all cgroup v1's members of struct mem_cgroup, struct mem_cgroup_per_node and struct task_struct under the CONFIG_MEMCG_V1 config option. If cgroup v1 support is not required (and it's true for many cgroup users these days), it allows to save a bit of memory and compile out some code, some of which is on relatively hot paths. It also structures the code a bit better by grouping cgroup v1-specific stuff in one place. This patch (of 9): memcg_account_kmem() consists of a trivial statistics change via mod_memcg_state() call and a relatively large memcg1-specific part. Let's factor out the mod_memcg_state() call and move the rest into the mm/memcontrol-v1.c file. Also rename memcg_account_kmem() into memcg1_account_kmem() for consistency.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
