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
