[PATCH 0/3] cgroup/cpuset: Remove redundant rebuild_sched_domains_locked() calls

[Waiman Long <longman@redhat.com>]

The main purpose of this series is to make sure that there will
be at most one rebuild_sched_domains_locked() call per cpuset
operation. Juri found that is still not the case. Make use of the
existing cpuset_force_rebuild() helper as a replacement for a direct
rebuild_sched_domains_locked() call and check force_sd_rebuild at the
operation end.

The last patch is for removing some unnecessary v1 specific code if
CONFIG_CPUSETS_V1 isn't set.

Waiman Long (3):
  cgroup/cpuset: Revert "Allow suppression of sched domain rebuild in
    update_cpumasks_hier()"
  cgroup/cpuset: Enforce at most one rebuild_sched_domains_locked() call
    per operation
  cgroup/cpuset: Further optimize code if CONFIG_CPUSETS_V1 not set
