v2:

• Fix test_cpuset_prs.sh problems reported by test robot
• Relax restriction imposed between cpuset.cpus.exclusive and cpuset.cpus of sibling cpusets.
• Make cpuset.cpus.exclusive independent of cpuset.cpus.
• Update test_cpuset_prs.sh accordingly.

[v1] https://lore.kernel.org/lkml/20240605171858.1323464-1-longman@redhat.com/

This patchset attempts to address the following cpuset issues.

1. While reviewing the generate_sched_domains() function, I found a bug in generating sched domains for remote non-isolating partitions.
2. Test robot had reported a test_cpuset_prs.sh test failure.
3. The current exclusivity test between cpuset.cpus.exclusive and cpuset.cpus and the restriction that the set effective exclusive CPUs has to be a subset of cpuset.cpus make it harder to preconfigure the cgroup hierarchy to enable remote partition.

The test_cpuset_prs.sh script is updated to match changes made in this patchset and was run to verify that the new code did not cause any regression.

Applied to cgroup/for-6.11.

Thanks.
