Re: [PATCH-cgroup 3/5] cgroup/cpuset: Eliminate unncessary sched domains rebuilds in hotplug

It was found that some hotplug operations may cause multiple rebuild_sched_domains_locked() calls. Some of those intermediate calls may use cpuset states not in the final correct form leading to incorrect sched domain setting.

Fix this problem by using the existing force_rebuild flag to inhibit immediate rebuild_sched_domains_locked() calls if set and only doing one final call at the end. Also renaming the force_rebuild flag to force_sd_rebuild to make its meaning for clear.

Applied to cgroup/for-6.11-fixes.

Thanks.
