My beef was with exactly that - too many things that do system tracing, none as good as DTrace. But I will take your word for it that eBPF will finally make it

My beef was with exactly that - too many things that do system tracing, none as good as DTrace. But I will take your word for it that eBPF will finally make it possible to have something closer to a good tracer like DTrace and all the other incompetent attempts will die off. Also: Thank you for working on Linux tracing - your blog posts have been very valuable to keep track of where it's all headed.
