<p>Hi LTTng:</p>
<p><br>
</p>
<p>Our service has been running overnight with LTTng enabled to do some memory consumption testing. We noticed the linux pmap output would have several memory map used by LTTng, and are marked as deleted. Do you know what are them? Why are they left in the
 system and marked as deleted? Thanks.<br>
