[PATCH 0/4] cgroup: Introduce cpu controller test suite

[David Vernet <void-gq6j2QGBifHby3iVrkZq2A@public.gmane.org>]

This patchset introduces a new test_cpu.c test suite as part of
tools/testing/selftests/cgroup. test_cpu.c will contain testcases that
validate the cgroup v2 cpu controller.

This patchset only contains testcases that validate cpu.stat and
cpu.weight, but I'm expecting to send further patchsets after this that
also include testcases that validate other knobs such as cpu.max.

Note that checkpatch complains about a missing MAINTAINERS file entry for
[PATCH 1/4], but Roman Gushchin added that entry in a separate patchset:
https://lore.kernel.org/all/20220415000133.3955987-4-roman.gushchin-fxUVXftIFDnyG1zEObXtfA@public.gmane.org/.
