            <title>[DOCS-8380] Add documentation on &quot;Metadata Locks&quot;</title>
                <link>https://jira.mongodb.org/browse/DOCS-8380</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;The output for db.currentOp() includes information for a class of locks named &quot;Metadata&quot;.&lt;/p&gt;

&lt;p&gt;The documentation describes these circularly as:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;&lt;b&gt;Metadata&lt;/b&gt; Represents metadata lock.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;More information on metadata locks, their meaning, and their implications, would be helpful.&lt;/p&gt;</description>
