Thanks Jonathan. Regarding to the CI MTTR/MTTF test results, it varies from 
time to time, and on master/stable branches. 
1. it monitors new Linux kernels, so the CI job may use newer kernel version 
than months ago?
2. What would be the criteria of MTBF here?

&gt; As you previously commented, “The current LTTng kernel tracer 
(lttng-modules) supports Linux 3.0+ only.” and we can find the support package 
list on http://packages.efficios.com/.&amp;nbsp;
&gt; Does LTTng have roadmap for upcoming new kernel versions?

I presume you are explicitly asking for RHEL &amp; SUSE kernels. The current
packages for these distro are maintained on a best effort and commercial
incentive of EfficiOS. If you are interested in supporting this effort please
contact sa...@efficios.com.

As for the actual upstream kernel, we are monitoring [1] all new kernels and
stable branches.
