Chen Ridong 6ee43047e8 cpuset: Remove unnecessary checks in rebuild_sched_domains_locked ... Commit 406100f3da ("cpuset: fix race between hotplug work and later CPU offline") added a check for empty effective_cpus in partitions for cgroup v2. However, this check did not account for remote partitions, which were introduced later. After commit 2125c0034c ("cgroup/cpuset: Make cpuset hotplug processing synchronous"), cpuset hotplug handling is now synchronous. This eliminates the race condition with subsequent CPU offline operations that the original check aimed to fix. Instead of extending the check to support remote partitions, this patch removes all the redundant effective_cpus check. Additionally, it adds a check and warning to verify that all generated sched domains consist of active CPUs, preventing partition_sched_domains from being invoked with offline CPUs.
