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!
