Realtime Linux: academia v. reality

SystemTap or uprobes? For SystemTap itself, it looks to me as though Frank and friends have worked around requiring anything they can avoid in the kernel itself. And done it pretty well given the stones laid in the path of anyone doing kernel modules outside the official kernel tree.

I thought I read about work to make SystemTap work with procfs. Any idea what is happening there (Frank?) Although something seems to be happening currently with uprobes, and Christoph Hellwig seemed to be actively (positively) involved in the discussion (see http://lkml.org/lkml/2010/7/27/121).

I'm not quite sure which effort you may be referring to.

Yes. It is unfortunate though that instructions of the form "Don't SYMBOL_EXPORT this facility [since you-know-who might use it]" are still the order of the day.
