Subject: [PATCH v5 1/9] audit: remove unnecessary NULL ptr checks from do_path_lookup
Date: Thu, 26 Jul 2012 07:21:05 -0400 [thread overview]
Message-ID: <1343301673-10642-2-git-send-email-jlayton@redhat.com> (raw)
In-Reply-To: <1343301673-10642-1-git-send-email-jlayton@redhat.com>
As best I can tell, whenever retval == 0, nd->path.dentry and nd->inode
are also non-NULL. Eliminate those checks and the superfluous
audit_context check.
