If KVM=y, it will select SCHEDSTATS, below erros can be seen: kernel/sched/stats.h: In function rq_sched_info_arrive: kernel/sched/stats.h:12:20: error: struct sched_info has no member named run_delay rq->rq_sched_info.run_delay += delta; ^ kernel/sched/stats.h:13:20: error: struct sched_info has no member named pcount rq->rq_sched_info.pcount++; ^ kernel/sched/stats.h: In function rq_sched_info_dequeued: kernel/sched/stats.h:31:20: error: struct sched_info has no member named run_delay rq->rq_sched_info.run_delay += delta; These are because CONFIG_SCHED_INFO is not set, This patch is to select SCHED_INFO before SCHEDSTATS.
