From: Tom Tucker Subject: [RFC,PATCH 05/38] svc: Move sk_sendto and sk_recvfrom to svc_xprt_class Date: Thu, 29 Nov 2007 16:55:48 -0600 Message-ID: <20071129225548.15275.72773.stgit@dell3.ogc.int> References: <20071129225510.15275.82660.stgit@dell3.ogc.int> Content-Type: text/plain; charset=utf-8; format=fixed Cc: linux-nfs@vger.kernel.org To: bfields@fieldses.org Return-path: Received: from 209-198-142-2-host.prismnet.net ([209.198.142.2]:47413 "EHLO smtp.opengridcomputing.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1762810AbXK2XUK (ORCPT ); Thu, 29 Nov 2007 18:20:10 -0500 In-Reply-To: <20071129225510.15275.82660.stgit-gUwIgmpLGaKNDNWfRnPdfg@public.gmane.org> Sender: linux-nfs-owner@vger.kernel.org List-ID: The sk_sendto and sk_recvfrom are function pointers that allow svc_sock to be used for both UDP and TCP. Move these function pointers to the svc_xprt_ops structure.
