[RFC 2/2] loopback: Enable TFO->complete_irq for fast-path ->scsi_done

From: Nicholas A. Bellinger
Date: Fri May 22 2015 - 04:00:27 EST


From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>

Go ahead and enable TFO->complete_irq for testing with loopback
LLD code, and avoid the extra fast-path queue_work() context
switch if no se_cmd special case handling requirements exist.
