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 225 sb-proc-25 /sys/fs/cgroup/system.slice/abrtd.service Link: https://lkml.kernel.org/r/20220601032227.4076670-6-roman.gushchin@linux.dev Signed-off-by: Roman Gushchin <roman.gushchin@linux.dev> Cc: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Cc: Dave Chinner <dchinner@redhat.com> Cc: Hillf Danton <hdanton@sina.com> Cc: Kent Overstreet <kent.overstreet@gmail.com> Cc: Muchun Song <songmuchun@bytedance.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
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.
