pub fn custom_cgroup_cpuset_add_remove(ctx: &Ctx<'_>) -> Result<AssertResult>Expand description
Add a third cpuset-partitioned cgroup mid-run; tear it down via automatic step boundary.
cg_0 / cg_1 hold their cpusets for the full scenario on the
Backdrop. cg_2 lives only in the middle Step — the automatic
step-boundary teardown removes it before the final hold runs,
replacing the pre-refactor explicit stop + remove ops.
