From: Richard Kennedy Subject: [PATCH] drm/ttm: remove padding from ttm_ref_object on 64bit builds Date: Tue, 26 Jan 2010 17:10:48 +0000 Message-ID: <1264525848.2044.5.camel@localhost> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: David Airlie , Thomas Hellstrom Cc: lkml , dri-devel@lists.sourceforge.net List-Id: dri-devel@lists.freedesktop.org Re-order structure ttm_ref_object to remove 8 bytes of alignment padding on 64 bit builds, so shrinking its size from 72 to 64 bytes allowing it to fit into a smaller slab.
