Peter might be able to fill us in on the details of the review progress of the uprobes patches. > ftrace focuses on the kernel. It will hopefully be integrated into the perf ABI soon, so that developers and users have a unified event platform for doing tracing, profiling, event logging and more - all of which go back to a very similar looking event platform. (Not sure what's holding up that process - there's no technical roadblocks really - it 'just has to be done'.)
