            <title>[SERVER-70486] Reduce the number of mutex locks in ClusterCursorManager</title>
                <link>https://jira.mongodb.org/browse/SERVER-70486</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are at least two cases where we can avoid some mutex locks in ClusterCursorManager class:&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;ClusterCursorStats::appendAtLeaf() calls ClusterCursorManager::stats() and ClusterCursorManager::cursorsTimedOut(), both of which require a mutex lock. For both methods appendAtLeaf() is the only caller, so we can combine them.&lt;/li&gt;
&lt;/ul&gt;


&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;ClusterCursorManager::killMortalCursorsInactiveSince locks two times, which also can be reduced to just one lock.&lt;/li&gt;
&lt;/ul&gt;
