Applied to cgroup/for-6.11. Thanks.
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.
