The last error is reported upstream as https://github.com/ktap/ktap/issues/80
and there seem not to have a fix available yet

----------------------------------------------------------------------------
Status|NEW |ASSIGNED

--- Comment #5 from Peter Korsgaard <[email protected]> --- Upstream ktap git has fixes for building against newer kernel versions (up to 4.8), so it makes more sense to bump the version. I've sent a patch doing that:

https://patchwork.ozlabs.org/patch/893750/

Notice that ktap upstream seems pretty dead, so consider using another tracing tool.
