v2: - Add a new patch 1 that fixes a bug introduced by recent v6.2 commit 7a2127e66a00 ("cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task"). - Make a small twist and additional comment to patch 2 ("cgroup/cpuset: Skip task update if hotplug doesn't affect current cpuset") as suggested by Michal. - Remove v1 patches 3/4 for now for further discussion.
This patch series includes miscellaneous update to the cpuset and its testing code.
Patch 1 fixes a bug caused by commit 7a2127e66a00 ("cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task") in the partition handling code. This fix was verified by running the test_cpuset_prs.sh test.
Patch 2 is for a hotplug optimization.
Patch 3 is actually a follow-up of commit 3fb906e7fabb ("cgroup/cpuset: Don't filter offline CPUs in cpuset_cpus_allowed() for top cpuset tasks").
Patch 4 reduces verbosity when running test_cpuset_prs.sh test script unless explicitly enabled with the -v option.
