First, thanks for your work!

In fact, I was working on the same topic of support SDT markers.  But I
started it by adding support for accessing arguments in uprobes [1].
The patchset is floating around the list for now but I hope it'll get
merged soon.  I guess you want to have it too :).

Anyway, it'd great if you add me to CC next time.

Thanks,
Namhyung
