From 8f3b8fa9afe75cafc4feb317d305444f6c5271fb Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 11 Jan 2007 14:15:12 -0800 Subject: [PATCH] [SCSI] aic94xx: Don't eat TMF_QUERY_TASK results In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK. The sequencer, it seems, is perfectly happy sending us a SSP response, which this function promptly "converts" into TMF_RESP_FUNC_FAILED. This leads to the SAS EH making bad decisions based on bad data, so we should not perform the conversion in this case. Signed-off-by: Darrick J.
