Not really. The utrace kernels Luming is trying are intended to match the vanilla ptrace behavior. I don't think it's very useful to worry about the difference between some utrace kernel and the current vanilla kernel. Let's just look at what the current vanilla kernel is doing and compare that to what an older vanilla kernel did if older versions produced different results for the test case.
Thanks, Roland
