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