__sched_period

函数名称：The idea is to set a period in which each task runs once.* When there are too many tasks (sched_nr_latency) we have to stretch* this period because otherwise the slices get too small.* p = (nr <= nl) ? l : l*nr/nl

函数原型：static u64 __sched_period(unsigned long nr_running)

返回类型：u64

参数：

类型	参数	名称
unsigned long	nr_running

679

如果此条件成立可能性小(为编译器优化)(nr_running > This value is kept at sysctl_sched_latency/sysctl_sched_min_granularity)则返回:nr_running乘Minimal preemption granularity for CPU-bound tasks:* (default: 0.75 msec * (1 + ilog(ncpus)), units: nanoseconds)

681

否则返回:Targeted preemption latency for CPU-bound tasks:* NOTE: this latency value is not the same as the concept of* 'timeslice length' - timeslices in CFS are of variable length* and have no persistent notion like in traditional, time-slice
