When a local partition becomes invalid, it won't transition back to valid partition automatically if a proper "cpuset.cpus.exclusive" or "cpuset.cpus" change is made. Instead, system administrators have to explicitly echo "root" or "isolated" into the "cpuset.cpus.partition" file at the partition root. This patch now enables the automatic transition of an invalid local partition back to valid when there is a proper "cpuset.cpus.exclusive" or "cpuset.cpus" change. Automatic transition of an invalid remote partition to a valid one, however, is not covered by this patch. They still need an explicit write to "cpuset.cpus.partition" to become valid again. The test_cpuset_prs.sh test script is updated to add new test cases to test this automatic state transition.
