                <link>https://jira.mongodb.org/browse/SERVER-39520</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Ensure that no places rely on database intent locks to ensure a Collection pointer renames valid.&lt;br/&gt;
Check that collection drop doesn&apos;t block on open transactions involving other collections in the same database.&lt;/p&gt;</description>
