This is a follow-up patch series to [1] to properly handle a special case for cpuset task migration operation where the source and destination cpusets are the same. Patch 1 handle this special cases by skipping tasks are not migrating with respect to cpuset. Patch 2 enables cpuset_*attach() to handle the case where thare many destination cpusets which when a cpuset controller is enabled. Patch 3 adds a new test case into test_cpuset to test proper handling of cpu affinity when cpuset controller is disabled.
