cgroup/cpuset: Add test for partition root invalidation returning wrong CPUs

Browse source

Add a test case to REMOTE_TEST_MATRIX covering the bug fixed by
commit 345f401666 ("cgroup/cpuset: Return only actually allocated
CPUs during partition invalidation"). The test verifies that when a
sibling partition root changes its cpuset.cpus to overlap with another
partition root, only actually allocated CPUs (effective_xcpus) are
returned to the parent, not all CPUs in cpus_allowed.
