函数名称：Account multiple ticks of idle time.*@ticks: number of stolen ticks

函数原型：void account_idle_ticks(unsigned long ticks)

返回类型：void

参数：

类型参数名称
unsigned longticks
510  如果SPDX-License-Identifier: GPL-2.0-only则
511  irqtime_account_idle_ticks(ticks)
512  返回
515  cputime等于ticks乘TICK_NSEC is the time between ticks in nsec assuming SHIFTED_HZ
516  steal等于When a guest is interrupted for a longer amount of time, missed clock* ticks are not redelivered later. Due to that, this function may on* occasion account more time than the calling functions think elapsed.
518  如果steal大于等于cputime则返回
521  cputime减等于steal
522  Account for idle time.*@cputime: the CPU time spent in idle wait
