Wow, thanks, I tried to search lkml for any presence of
patches/discussion about these slides, but couldn't find anything, thanks for
pointing it out.

I really like 'blocking/preempted' indication and of course I miss
pointers decoding.

Did anyone really think about decoding pointers and how we can
implement it (like dumping them upon entering a syscall and then
using inside the perf trace?)?
