By the way, note that we also need to annotate the exit ones. To do
something similar, for __exit we have:
#define __exit __section(.exit.text) __exitused __cold notrace
__exitused expands to nothing when MODULE is defined.
notrace is either hotpatch(0,0) or no_instrument_function; and they
shouldn't matter in the alias since we are not generating code (and
anyway they disable the extra code, instead of enabling).
So I will also use __exit there instead of only __cold too.
Cheers,
Miguel
