H A D | stop_task.c | diff 72465447867b9de6b5cdea5d10f9781585136270 Thu May 08 18:00:14 CDT 2014 Kirill Tkhai <tkhai@yandex.ru> sched, nohz: Change rq->nr_running to always use wrappers
Sometimes ->nr_running may cross 2 but interrupt is not being sent to rq's cpu. In this case we don't reenable the timer. Looks like this may be the reason for rare unexpected effects, if nohz is enabled.
Patch replaces all places of direct changing of nr_running and makes add_nr_running() caring about crossing border.
