函数名称:stop_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
函数原型:int stop_machine_from_inactive_cpu(cpu_stop_fn_t fn, void *data, const struct cpumask *cpus)
