[nvmewin] StartIo Function Return value for NVMePowerControl

[Chang, Alex]

Hi Ravi,

For SRB_FUNCTION_POWER requests, NVMeStartIo always returns TRUE (Line 1205 in nvmestd.c) to indicate the request had been successfully initiated/processed. I am not sure why you mentioned it returns FALSE to Storport driver?

Thanks,
Alex

Hi,

As per observation on Windows the function NVMeStarIo(NVMeStd.c) for Power management, in case NVMePowerControl()
returns false it is still completed the request in NVMeStartIo and returns FALSE to StorPort driver. Whereas in case of StartIo returns FALSE StorPort driver treats IO has some issue and try to complete its own in AdapterControl call which create the BSOD to system (Multiple_IO_Request_Complete error).
  Don't we required to put the check in case failure of handle the power management system need not to be complete the Io as PortDriver makes it complete its own.
