类型参数名称
const struct cpumask *cpumask
cpu_stop_fn_tfn
void *arg
struct cpu_stop_done *done
380  bool queued = false
387  禁止抢占()
388  stop_cpus_in_progress = true
389  The "volatile" is due to gcc bugs ()
391  work等于per_cpu(stop_work, cpu)
392  fn等于fn
393  arg等于arg
394  done等于done
395  如果queue @work to @stopper. if offline, @work is completed immediately 则queued = true

__stop_cpus
stop_machine_from_inactive_cpustop_machine_from_inactive_cpu - stop_machine() from inactive CPU*@fn: the function to run*@data: the data ptr for the @fn()*@cpus: the cpus to run the @fn() on (NULL = any online cpu)* This is identical to stop_machine() but can be called from a CPU which
