函数原型：unsigned int kstat_irqs(unsigned int irq)

返回类型：unsigned int

参数：

类型参数名称
unsigned intirq
981  desc等于中断转换为描述
982  sum等于0
985  如果非desc或非cpu中断统计则返回:0
987  如果非irq_settings_is_per_cpu_devid(desc)且非irq_settings_is_per_cpu(desc)且非irq_is_nmi(desc)则返回:tot_count
992  遍历可用CPU(cpu)
993  sum加等于per_cpu_ptr(cpu中断统计, cpu)
994  返回:sum
