[PATCH 0/4] sched/smt: Fix error handling in sched_cpu_deactivate()

[Yang Yingliang]

From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

sched_smt_present decrement and set_rq_offline() is called before
cpuset_cpu_inactive(), if cpuset_cpu_inactive() fails, these two
things need be rollback.

Yang Yingliang (4):
  sched/smt: Introduce sched_smt_present_inc/dec() helper
  sched/smt: fix unbalance sched_smt_present dec/inc
  sched/core: Introduce sched_set_rq_on/offline() helper
  sched/core: fix unbalance set_rq_online/offline() in
    sched_cpu_deactivate()
