This service is issued by DeviceFS when an open attempt on a device cannot be complete.
The reason for this service call being issued by DeviceFS are:
Hopefully sufficient blocking streams can be closed, which will allow the open request to be fulfilled. If you opened the stream in R2, and it need no longer be kept open, then you should close it and claim the service. The kernel responds to this service to close the printer and serial devices if it has implicitly opened them.
