The tick when exit idle for nohz_full cpu

Hi, Frederic I noticed currently the tick_nohz_idle_exit() will always restart the sched_tick, even when it's on the nohz_full cpu. I'm not sure if we can keep the sched_tick stopped if it's on a nohz_full_cpu. The sched tick will be enabled on tick_nohz_task_switch() if needed. Is it

Set the idle_exittime on tick_nohz_restart_sched_tick

Hi, Frederic I noticed on latest code, the tick_nohz_restart_sched_tick() set the ts->idle_exittime, should it be done on tick_nohz_stop_idle() since the tick_nohz_restart_sched_tick() is invoked also on nohz_full scenario, am I right, or do I miss anything? Thanks --jyh -- To
