Message-ID: <512D90F2.9070200@asianux.com> Date: Wed, 27 Feb 2013 12:52:02 +0800 From: Chen Gang <gang.chen@...anux.com> To: konrad.wilk@...cle.com, roger.pau@...rix.com, jbeulich@...e.com, stefano.stabellini@...citrix.com, dgdegra@...ho.nsa.gov, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH] drivers/block/xen-blkback: preq.dev is used without initialized if call xen_vbd_translate failed, the preq.dev will be not initialized. so use blkif->vbd.pdevice instead (still better to print relative info).
