Hi Alexandre,

Since there has been an important tracepoint module API change between 3.14
and 3.15 in the Linux kernel, supporting 3.15 falls into the "new feature"
category, so we don't plan to backport it to stable 2.4.

lttng-modules 2.5.0 (currently at RC1) is what you need there.

Thanks!

Mathieu
