Subject: [PATCH 13/29] ioat1: kill unused unmap parameters
Date: Thu, 03 Sep 2009 19:31:36 -0700 [thread overview]
Message-ID: <20090904023136.32667.56906.stgit@dwillia2-linux.ch.intel.com> (raw)
In-Reply-To: <20090904022733.32667.77626.stgit@dwillia2-linux.ch.intel.com>
The unified ioat1/ioat2 ioat_dma_unmap() implementation derives the
source and dest addresses from the unmap descriptor. There is no longer
a need to track this information in struct ioat_desc_sw.
