I think this is rather ugly and harder to maintain. The whole _point_ of
such annotations is to make them 'easy on the eyes', to make it easy to
skip a 'noinline', 'noprobe' or 'notrace' tag.
Using something like NOKPROBE_SYMBOL() makes the whole construct ugly and
attention seeking.
So until compilers get smarter (or there's some compiler trick I haven't
noticed) lets stay with the separate section - it's not the end of the
world, the (effective) 'noinline' aspect of noprobes changes code
generation anyway.
Thanks,
Ingo
