cpuset: fix warning when disabling remote partition

A warning was triggered as follows:

Reproduction steps (on a 16-CPU machine):

# cd /sys/fs/cgroup/ # mkdir A1 # echo +cpuset > A1/cgroup.subtree_control # echo "0-14" > A1/cpuset.cpus.exclusive # mkdir A1/A2 # echo "0-14" > A1/A2/cpuset.cpus.exclusive # echo "root" > A1/A2/cpuset.cpus.partition # echo 0 > /sys/devices/system/cpu/cpu15/online # echo member > A1/A2/cpuset.cpus.partition

When CPU 15 is offlined, subpartitions_cpus gets cleared because no CPUs remain available for the top_cpuset, forcing partitions to share CPUs with the top_cpuset. In this scenario, disabling the remote partition triggers a warning stating that effective_xcpus is not a subset of subpartitions_cpus. Partitions should be invalidated in this case to inform users that the partition is now invalid(cpus are shared with top_cpuset).

To fix this issue:

  • Only emit the warning only if subpartitions_cpus is not empty and the
effective_xcpus is not a subset of subpartitions_cpus.
  • During the CPU hotplug process, invalidate partitions if
subpartitions_cpus is empty.
