            <title>[LU-16123] checkpatch: comparisons with a constant or upper case identifier on the left</title>
                <link>https://jira.whamcloud.com/browse/LU-16123</link>
                <project id="10000" key="LU">Lustre</project>
                    <description>&lt;p&gt;checkpatch trows a warning if it finds an &quot;UPPERCASE&quot; on the left and side.&#160; According to the script/code it is to avoid cases like &quot;foo + BAR &amp;lt; baz&quot;.&lt;/p&gt;

&lt;p&gt;However for our case&#160; &quot;#if LUSTRE_VERSION_CODE &amp;lt; OBD_OCD_VERSION(3, 0, 53, 0)&quot; this warning is false positive.&lt;/p&gt;

&lt;p&gt;This could be recreated as:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;
&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
