Guise? They distributed source and the patch is not at all obfuscated.  Eight consecutive lines like &quot;cred-&gt;uid = 0;&quot; and then printk(&quot;now you are root\n&quot;), so it&#x27;s really easy to spot in a diff.<p>Don&#x27;t see why they did it, but they did in in the plainest and most visible way I can imagine.
