The LTTng modules provide Linux kernel tracing capability to the LTTng tracer toolset.
Those versions are bugfixes in the currently maintained stable branches of lttng-modules. They mainly contain: - Fix for the "PID tracker" feature, which should track pgid, which corresponds to the notion of process ID in user-space. It is now in sync with the feature in the UST tracing domain (application tracing), - Adding a "flush empty" ioctl for snapshots fixes cases where the Babeltrace lttng-live reader has issues keeping up with a steady stream of useless empty packets. This "flush empty" ioctl is introduced in backwards and forwards compatible ways, to ensure smooth upgrade within the stable versions of lttng-tools and lttng-modules. Those releases also add support for 4.12 release candidate kernels. Enjoy!
