Patch series "memcg: add pagetable comsumption to memory.stat", v2. Many workloads consumes significant amount of memory in pagetables. One specific use-case is the user space network driver which mmaps the application memory to provide zero copy transfer. This driver can consume a large amount memory in page tables. This patch series exposes the pagetable comsumption for each memory cgroup. This patch (of 2): This does not change any functionality and only move the functions which update the lruvec stats to vmstat.h from memcontrol.h. The main reason for this patch is to be able to use these functions in the page table contructor function which is defined in mm.h and we can not include the memcontrol.h in that file. Also this is a better place for this interface in general. The lruvec abstraction, while invented for memcg, isn't specific to memcg at all.

README
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.
