Roman Gushchin d261ea2353 tools: add memcg_shrinker.py 
Add a simple tool which prints a sorted list of shrinker lists in the
following format: (number of objects, shrinker name, cgroup).

Example:
  $ ./memcg_shrinker.py -n 10
  2090     sb-sysfs-26          /sys/fs/cgroup/system.slice
  1809     sb-sysfs-26          /sys/fs/cgroup/system.slice/systemd-udevd.service
  1044     sb-btrfs:vda2-24     /sys/fs/cgroup/system.slice/system-dbus\x2d:1.3\...
  861      sb-btrfs:vda2-24     /sys/fs/cgroup/system.slice/system-dbus\x2d:1.3\...
  804      sb-btrfs:vda2-24     /sys/fs/cgroup/system.slice
  643      sb-btrfs:vda2-24     /sys/fs/cgroup/system.slice/firewalld.service
  616      sb-cgroup2-30        /sys/fs/cgroup/init.scope
  275      sb-sysfs-26          /
  238      sb-proc-25           /sys/fs/cgroup/system.slice/systemd-journald.service

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.
