Subject: [56/66] [SCSI] libsas: fix NCQ mixing with non-NCQ
Date: Fri, 19 Nov 2010 14:01:27 -0800 [thread overview]
Message-ID: <20101119220126.795606110@clark.site> (raw)
In-Reply-To: <20101119220309.GA15562@kroah.com>
2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------
From: David Milburn <dmilburn@redhat.com>
commit f0ad30d3d2dc924decc0e10b1ff6dc32525a5d99 upstream.
Some cards (like mvsas) have issue troubles if non-NCQ commands are
mixed with NCQ ones. Fix this by using the libata default NCQ check
routine which waits until all NCQ commands are complete before issuing
a non-NCQ one. The impact to cards (like aic94xx) which don't need
this logic should be minimal
