返回类型：ssize_t

参数：

类型参数名称
struct kobject *kobj
struct kobj_attribute *attr
const char *buf
size_tn
1054  len等于n
1057  如果len且buf[len - 1]恒等于'\n'则len自减
1059  name等于kstrndup(buf, len, GFP_KERNEL)
1060  如果非name则返回:负ENOMEM
1063  res等于name_to_dev_t(name)
1064  释放内存
1065  如果非res则返回:负EINVAL
1068  lock_system_sleep()
1069  swsusp_resume_device等于res
1070  unlock_system_sleep()
1071  pm_pr_dbg("Configured resume from disk to %u\n", swsusp_resume_device)
1072  noresume等于0
1073  software_resume - Resume from a saved hibernation image.* This routine is called as a late initcall, when all devices have been* discovered and initialized already.* The image reading code is called to see if there is a hibernation image
