This is one case where I don't think the change\nis worth it. The structure is a little smaller, but this structure is\ngenerally on the stack and often part of union dpif_op, and I think that\nmoving pmd_id to the beginning of the struct makes it look more\nimportant than it is. So, I'm going to skip this one.","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","dev@openvswitch.org"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","ovs-dev@mail.linuxfoundation.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=openvswitch.org\n\t(client-ip=140.211.169.12; helo=mail.linuxfoundation.org;\n\tenvelope-from=ovs-dev-bounces@openvswitch.org;\n\treceiver=)","Received":["from mail.linuxfoundation.org (mail.linuxfoundation.org\n\t[140.211.169.12])\n\t(using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256\n\tbits)) (No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3yTCYC6FfTz9sBW\n\tfor ;\n\tSat, 4 Nov 2017 07:02:39 +1100 (AEDT)","from mail.linux-foundation.org (localhost [127.0.0.1])\n\tby mail.linuxfoundation.org (Postfix) with ESMTP id BAFC4AAB;\n\tFri, 3 Nov 2017 20:02:36 +0000 (UTC)","from smtp1.linuxfoundation.org (smtp1.linux-foundation.org\n\t[172.17.192.35])\n\tby mail.linuxfoundation.org (Postfix) with ESMTPS id 4E291AAB\n\tfor ; Fri, 3 Nov 2017 20:02:35 +0000 (UTC)","from relay5-d.mail.gandi.net (relay5-d.mail.gandi.net\n\t[217.70.183.197])\n\tby smtp1.linuxfoundation.org (Postfix) with ESMTPS id DDD7F54D\n\tfor ; Fri, 3 Nov 2017 20:02:34 +0000 (UTC)","from ovn.org (unknown [208.91.3.26])\n\t(Authenticated sender: blp@ovn.org)\n\tby relay5-d.mail.gandi.net (Postfix) with ESMTPSA id 7AD5141C084;\n\tFri, 3 Nov 2017 21:02:30 +0100 (CET)"],"X-Greylist":"domain auto-whitelisted by SQLgrey-1.7.6","X-Originating-IP":"208.91.3.26","Date":"Fri, 3 Nov 2017 13:02:27 -0700","From":"Ben Pfaff ","To":"Bhanuprakash Bodireddy ","Message-ID":"<20171103200227.GC27530@ovn.org>","References":"<1504893565-110166-1-git-send-email-bhanuprakash.bodireddy@intel.com>\n\t<1504893565-110166-10-git-send-email-bhanuprakash.bodireddy@intel.com>","MIME-Version":"1.0","Content-Disposition":"inline","In-Reply-To":"<1504893565-110166-10-git-send-email-bhanuprakash.bodireddy@intel.com>","User-Agent":"Mutt/1.5.23 (2014-03-12)","X-Spam-Status":"No, score=-0.7 required=5.0 tests=RCVD_IN_DNSWL_LOW\n\tautolearn=disabled version=3.3.1","X-Spam-Checker-Version":"SpamAssassin 3.3.1 (2010-03-16) on\n\tsmtp1.linux-foundation.org","Cc":"dev@openvswitch.org","Subject":"Re: [ovs-dev] [PATCH 09/13] dpif: Reorder elements in dpif_flow_put\n\tstructure.","X-BeenThere":"ovs-dev@openvswitch.org","X-Mailman-Version":"2.1.12","Precedence":"list","List-Id":"","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Content-Type":"text/plain; charset=\"us-ascii\"","Content-Transfer-Encoding":"7bit","Sender":"ovs-dev-bounces@openvswitch.org","Errors-To":"ovs-dev-bounces@openvswitch.org"}}]
