Unfortunately the inner declaration of error was not removed. Resulting in a version of __dentry_path that will never return an error. Remove the problematic inner declaration of error and allow __dentry_path to return errors once again. Cc: stable@vger.kernel.org Cc: Waiman Long Signed-off-by: "Eric W.
