LTTng creator Mathieu Desnoyers seems a
bit trapped in something of a catch-22.
At the 2026 Linux Plumbers Conference
(LPC), he led a discussion on the problem he is having in trying to
collaborate with other tracing projects (e.g. ftrace, perf) in the kernel. The
feedback he has gotten, both over the years and more recently, does not
show a path that would allow him to contribute the 21-year-old
GPLv2-licensed LTTng tracing framework, or, incrementally, features from
it, to the mainline kernel.
