Radostin Stoyanov 3a901bcc52 cgroup: Do not report unavailable v1 controllers in /proc/cgroups
JIRA: https://issues.redhat.com/browse/RHEL-80382

commit af000ce85293b8e608f696f0c6c280bc3a75887f
Author: Michal Koutný <mkoutny@suse.com>

    cgroup: Do not report unavailable v1 controllers in /proc/cgroups

    This is a followup to CONFIG-urability of cpuset and memory controllers
    for v1 hierarchies. Make the output in /proc/cgroups reflect that
    !CONFIG_CPUSETS_V1 is like !CONFIG_CPUSETS and
    !CONFIG_MEMCG_V1 is like !CONFIG_MEMCG.

    The intended effect is that hiding the unavailable controllers will hint
    users not to try mounting them on v1.

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.
