            <title>[SERVER-38440] Remove unnecessary UninterruptibleLockGuards from sharding code</title>
                <link>https://jira.mongodb.org/browse/SERVER-38440</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are four places in src/mongo/db/s/ that we can remove the use of &lt;tt&gt;UninterruptibleLockGuard&lt;/tt&gt; because they are unnecessary and would conflict with prepared transactions based on the locks they take.&#160;&lt;/p&gt;

&lt;p&gt;The first is in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/dcf7e0dd89d34f58b592f1adb3d41e5edd6e2012/src/mongo/db/s/migration_source_manager.cpp#L248&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;migration_source_manager.cpp&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The other three are in move_primary_source_manager.cpp &lt;a href=&quot;https://github.com/mongodb/mongo/blob/86fab3ee0e1570c6743b314fddc0af418bba9015/src/mongo/db/s/move_primary_source_manager.cpp#L90&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/86fab3ee0e1570c6743b314fddc0af418bba9015/src/mongo/db/s/move_primary_source_manager.cpp#L144&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/86fab3ee0e1570c6743b314fddc0af418bba9015/src/mongo/db/s/move_primary_source_manager.cpp#L194&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;</description>
