返回类型：ssize_t

参数：

类型参数名称
struct device *dev
struct device_attribute *attr
const char *buf
size_tcount
849  test_dev等于dev_to_test_dev(dev)
852  mutex_lock( & trigger_mutex)
853  mutex_lock( & config_mutex)
855  ret等于__kmod_config_init(test_dev)
856  如果ret小于0则
857  ret等于负ENOMEM
858  dev_err(dev, "could not alloc settings for config trigger: %d\n", ret)
860  转到:out
863  dev_info(dev, "reset\n")
864  ret等于count
866  out :
867  mutex_unlock( & config_mutex)
868  mutex_unlock( & trigger_mutex)
870  返回:ret
