The irqtime is accounted is nsecs and stored in cpu_irq_time.hardirq_time and cpu_irq_time.softirq_time. Once the accumulated amount reaches a new jiffy, this one gets accounted to the kcpustat. This was necessary when kcpustat was stored in cputime_t, which could at worst have jiffies granularity. But now kcpustat is stored in nsecs so this whole discretization game with temporary irqtime storage has become unnecessary. We can now directly account the irqtime to the kcpustat. Signed-off-by:
