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@xxxxxxxxxx/
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.
