            <title>[SERVER-39960] Simplify OpCtx::markKilled</title>
                <link>https://jira.mongodb.org/browse/SERVER-39960</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Operation context currently relies on an elaborate dance between the client lock, _waitMutex, _waitCV and _numKillers to allow markKilled to tap the condvar an opctx is waiting on.&lt;/p&gt;

&lt;p&gt;After the introduction of batons on all opctx&apos;s, this is no longer necessary (as batons have their own support for being woken, while waiting on a condvar).  Removing the special killing code will simplify opctx, and remove a lot of extra book keeping.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-39960&quot; title=&quot;Simplify OpCtx::markKilled&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-39960&quot;&gt;&lt;del&gt;SERVER-39960&lt;/del&gt;&lt;/a&gt; Simplify opCtx::markKilled&lt;/p&gt;

&lt;p&gt;Operation context currently relies on an elaborate dance between the&lt;br/&gt;
client lock, _waitMutex, _waitCV and _numKillers to allow markKilled to&lt;br/&gt;
tap the condvar an opctx is waiting on.&lt;/p&gt;

&lt;p&gt;After the introduction of batons on all opctx&apos;s, this is no longer&lt;br/&gt;
necessary (as batons have their own support for being woken, while&lt;br/&gt;
waiting on a condvar). Removing the special killing code will simplify&lt;br/&gt;
opctx, and remove a lot of extra book keeping.&lt;br/&gt;
