It covers the three currently active lttng-modules branches: the 2.9 and 2.10 stable branches, as well as the 2.11 branch in release candidate cycle. Those releases add support for kernel 4.19. One important improvement is to prevent allocation of buffers larger than the available memory, which can cause the OOM killer to trigger. Even if the OOM killer end up having to trigger, the current OOM kill target is set to the current thread while allocating buffers. Enjoy!
