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.
