TS_POLLING set tells the scheduler an idle_task will poll need_resched() to look for work. TS_POLLING clear tells resched_task() and wake_up_idle_cpu() that the remote CPU's idle_task is now sleeping in idle, and thus requires a reschedule interrupt notice work. Update the description of TS_POLLING to reflect how it works. "idle task polling need_resched, skip sending interrupt" Wordsmithing-by: Milton Miller <miltonm@bga.com> Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Peter Zijlstra <peterz@infradead.org> |
