struct seq_file *m
intcpu
616  rq等于cpu_rq(cpu)
627  This allows printing both to /proc/sched_debug and* to the console(m, "cpu#%d\n", cpu)
641  P(r_running and nr_context_switches:* externally visible scheduler statistics: current number of runnable* threads, total number of context switches performed since bootup.)
642  P(nr_switches)
643  P(nr_load_updates)
644  P(nr_uninterruptible)
645  PN(next_balance)
646  This allows printing both to /proc/sched_debug and* to the console(m, " .%-30s: %ld\n", "curr->pid", (long)(task_pid_nr(当前任务)))
647  PN(clock)
648  PN(clock_task)
