Tracer missing kernels in latest dev on Ubuntu > 18.04

[JRPan]

The tracer traces out every kernel (kernel-*.trace), but after post-processing, only the first kernel is processed. Other traceg files are empty.

This happened after the introduction of the compress feature.
We are working on that right now.
For now, please use commit 53da2df instead if you want to use the tracer.
git checkout 53da2df

Thanks
