[PATCH v2 0/2] docs: cgroup-v2: Correct cpuset CPU descriptions
From: Guopeng Zhang

From: Guopeng Zhang <zhangguopeng@xxxxxxxxxx>
The cpuset interface documentation says cpuset.cpus.isolated is empty
unless an isolated partition exists, omitting CPUs isolated at boot with
isolcpus=domain. Its cpuset.cpus.effective description also assumes CPUs
come from the immediate parent and are normally a subset of
cpuset.cpus, which is not always true for valid non-root partition roots.
Update both descriptions to match the existing behavior.
Changes since v1:
- Reword the cpuset.cpus.isolated description as suggested, while
specifying the domain flag of isolcpus.
- Add examples of the cpuset.cpus.effective relationship for member or
invalid partition roots and for valid partition roots.
- Add the Suggested-by tags and the Reviewed-by tag.
