From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dan Williams Subject: [PATCH 13/29] ioat1: kill unused unmap parameters Date: Thu, 03 Sep 2009 19:31:36 -0700 Message-ID: <20090904023136.32667.56906.stgit@dwillia2-linux.ch.intel.com> References: <20090904022733.32667.77626.stgit@dwillia2-linux.ch.intel.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: linux-raid@vger.kernel.org, netdev@vger.kernel.org, Maciej Sosnowski To: linux-kernel@vger.kernel.org Return-path: In-Reply-To: <20090904022733.32667.77626.stgit@dwillia2-linux.ch.intel.com> Sender: linux-raid-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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.
