Please don't base distributions on -rc tags. They are not meant for this. We always integrate support for newer kernel versions instrumentation back into our current stable release. So as soon as 5.2 final comes out, we will release a 2.10.x version including support for it in lttng-modules. The current 2.10.10 has commits to support the currently known 5.2-rc instrumentation changes. Thanks, Mathieu > >> Cheers, >> >> Richard > > cu > Adrian > > -- > > "Is there not promise of rain?"
