I'm tracing all of the initcalls in my machine (even the modules).
If you look at both svg sources, you will see all of the 5 initcalls displayed.
But for the "before the patch" one, it depends on the software you are
using to visualize it.
With firefox you only see two of them. With the default gnome
visualization software (don't remember its name)
you can see all of them but in a very extensive image because a lot of
rows are unused.

With the "after the patch one", there is no issues....
