In this scenario, disabling the remote partition triggers\na warning stating that effective_xcpus is not a subset of\nsubpartitions_cpus. Partitions should be invalidated in this case to\ninform users that the partition is now invalid(cpus are shared with\ntop_cpuset).\n\nTo fix this issue:\n1. Only emit the warning only if subpartitions_cpus is not empty and the\n   effective_xcpus is not a subset of subpartitions_cpus.\n2. During the CPU hotplug process, invalidate partitions if\n   subpartitions_cpus is empty.",
