We can shrink sg_lb_stats because rq::nr_running is an unsigned int and cpu numbers are 'int' Before: sgs: /* size: 72, cachelines: 2, members: 10 */ sds: /* size: 184, cachelines: 3, members: 7 */ After: sgs: /* size: 56, cachelines: 1, members: 10 */ sds: /* size: 152, cachelines: 3, members: 7 */ Further we can avoid clearing all of sds since we do a total clear/assignment of sg_stats in update_sg_lb_stats() with exception of busiest_stat.avg_load which is referenced in update_sd_pick_busiest().
