Subject: [patch] [SCSI] target: checking for NULL instead of IS_ERR
Date: Sat, 15 Jan 2011 14:03:00 +0000 [thread overview]
Message-ID: <20110115140300.GC2721@bicker> (raw)
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.
