函数原型：static void psi_avgs_work(struct work_struct *work)

返回类型：void

参数：

类型参数名称
struct work_struct *work
418  dwork等于to_delayed_work(work)
419  group等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(dwork, structpsi_group, avgs_work)
421  mutex_lock( & avgs_lock)
423  now等于Scheduler clock - returns current time in nanosec units.* This is default implementation.* Architectures and sub-architectures can override this.
425  collect_percpu_times(group, PSI_AVGS, & changed_states)
426  nonidle等于changed_states按位与1左移PSI_NONIDLE位
434  如果now大于等于avg_next_update则avg_next_update等于update_averages(group, now)
437  如果nonidle则
438  在延迟工作队列中放置任务
442  mutex_unlock( & avgs_lock)
