函数名称：test_suspend

函数原型：static int __init test_suspend(void)

返回类型：int

参数：无

181  static char warn_no_rtc[] __initdata = warning conditions  "PM: no wakealarm-capable RTC driver is ready\n"
184  struct rtc_device * rtc = NULL
189  如果非Kernel options like "test_suspend=mem" force suspend/resume sanity tests* at startup time. They're normally disabled, for faster boot and because* we can't know which states really work on this particular system.则返回:0
192  以test_state小于PM_SUSPEND_MAX循环
193  state_label等于pm_states[test_state]
195  如果state_label且非字符串比较则退出
198  如果test_state恒等于PM_SUSPEND_MAX则
199  printk(warn_bad_state, Kernel options like "test_suspend=mem" force suspend/resume sanity tests* at startup time. They're normally disabled, for faster boot and because* we can't know which states really work on this particular system.)
200  返回:0
204  dev等于class_find_device(rtc_class, NULL, NULL, has_wakealarm)
205  如果dev则
206  rtc等于rtc_class_open(dev_name(dev))
207  put_device(dev)
209  如果非rtc则
210  printk(warn_no_rtc)
211  返回:0
215  To test system suspend, we need a hands-off mechanism to resume the* system. RTCs wake alarms are a common self-contained mechanism.
216  rtc_class_close(rtc)
217  返回:0
