Yes, but for UST, it's sizeof(struct probe), actually almost the same but
different name :P

This was introduce in UST from commit (in libust/tracepoint.c)

I really have NO idea how it came in because for that commit I only changed the
malloc to zmalloc. So I think, somekind of "merge" between patches went wrong
and git didn't notice. Shit happens ;)

Thanks
