Test cgroup v2 freezer time stat. Freezer time accounting should be independent of other cgroups in the hierarchy and should increase iff a cgroup is CGRP_FREEZE (regardless of whether it reaches CGRP_FROZEN). Skip these tests on systems without freeze time accounting. Signed-off-by: Tiffany Yang <ynaffit@google.com> Cc: Michal Koutný <mkoutny@suse.com> Signed-off-by: Tejun Heo <tj@kernel.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 reStructuredText 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.
