Date: Sat, 15 Jan 2011 17:03:00 +0300 From: Dan Carpenter <error27@...il.com> To: "Nicholas A. Bellinger" <nab@...ux-iscsi.org> Cc: James Bottomley <James.Bottomley@...e.de>, linux-kernel@...r.kernel.org, linux-scsi@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [patch] [SCSI] target: checking for NULL instead of IS_ERR blkdev_get_by_path() returns an ERR_PTR() or error and it doesn't return a NULL. It looks like this bug would be easy to trigger by mistake.
