cgroup: Fixes for v6.11-rc4
Three patches addressing cpuset corner cases.
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.
