Probably not. Better to keep it local to lttng-dev at lists.lttng.org,
since LTTng has been removed from Linux staging. Mainline Linux seems to
focus on perf/ftrace nowadays. By the way, if you have patches that
change the Linux kernel, we'll need to modify them so the ABIs exposed
go through the /proc/lttng ioctls and mmap.

Thanks,

Mathieu
