From b4efdd586bc08cdf5977cad0a90091f44546a930 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 9 Apr 2009 15:57:10 -0500 Subject: [PATCH] [SCSI] fix q->lock not held warning when target is busy We cannot call blk_plug_device from scsi_target_queue_ready because the q lock is not held. And we do not need to call it from there because when we return 0, the scsi_request_fn not_ready handling will plug the queue for us if needed.
