Hello,
This is a part of my work to improve perf annotate. At first, I'd like reduce the size of struct annotation which will be allocated together with struct symbol in some cases. In fact, it doesn't use most of them so it needs to slim down and lazy-allocate used part.
* v2 changes) - fix typo - reorder struct annotated_source - add Ian's Reviewed-by tags
With this applied, size of the struct goes down from 96 to 48.
The code is available at perf/annotate-diet-v2 branch in
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks, Namhyung
