return value queuecommand should return after an unplug

return value queuecommand should return after an unplug

[Oliver Neukum]

Hi,

I am looking at the queuecommand() mathod of the UAS low
level driver. What is a host adaptor driver to do when
it gets a scsi request for an unplugged host adapter?

All teh return values I see say that something is busy.
But I have the case that something is dead and gone.

	Regards
		Oliver

Hi Oliver,

I think that the SCSI result has to be set to an appropriate error code, 
that >scsi_done() has to be called and that queuecommand() has to return 
0 (success) in this case. Examples can be found in virtscsi_complete_cmd().
