<div style="font-size: 12px;">Hi,</div>
<div style="font-size: 12px;">I am from Ericsson and we are trying to use lttng for one of our routing stack module. We are facing issue in using lttng with our code base. We are facing crash in our module when we register tracepoints. We are using lttng
version 2.3.0. Any input will be appreciated. Thanks in advance.</div>
