From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Marciniszyn Subject: [PATCH v3] IB/ipath: remove ib_sg_dma_address() and ib_sg_dma_len() overloads Date: Fri, 28 Mar 2014 15:04:43 -0400 Message-ID: <20140328190443.16637.90651.stgit@phlsvslse11.ph.intel.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: roland-BHEL68pLQRGGvPXPguhicg@public.gmane.org Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Christoph Raisch , Hoang-Nam Nguyen , Bart Van Assche List-Id: linux-rdma@vger.kernel.org The lack of these methods is compensated for by code changes to .map_sg to insure that the vanilla sg_dma_address() and sg_dma_len() will do the same thing as the equivalent former ib_sg_dma_address() and ib_sg_dma_len() calls into the drivers. The introduction of this patch required that the struct ipath_dma_mapping_ops be converted to C99 initializer.
