Patch series "memcg: reduce memory overhead of memory cgroups". Currently a lot of memory is wasted to maintain the vmevents for memory cgroups as we have multiple arrays of size NR_VM_EVENT_ITEMS which can be as large as 110. However memcg code uses small portion of those entries. This patch series eliminate this overhead by removing the unneeded vmevent entries from memory cgroup data structures. This patch (of 3): This is a preparatory patch to reduce the memory overhead of memory cgroup. The struct memcg_vmstats is the largest object embedded into the struct mem_cgroup. This patch extracts struct memcg_vmstats from struct mem_cgroup to ease the following patches in reducing the size of struct memcg_vmstats.

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 Restructured Text 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.
