Peter Zijlstra c82513e513 sched: Change rq->nr_running to unsigned int ... Since there's a PID space limit of 30bits (see futex.h:FUTEX_TID_MASK) and allocating that many tasks (assuming a lower bound of 2 pages per task) would still take 8T of memory it seems reasonable to say that unsigned int is sufficient for rq->nr_running. When we do get anywhere near that amount of tasks I suspect other things would go funny, load-balancer load computations would really need to be hoisted to 128bit etc. So save a few bytes and convert rq->nr_running and friends to unsigned int.
