OK. I just figured that I could initialize the rcu_heads in all cases in the
debugobject fixup anyway, so I guess I won't need "object_is_static()" after
all. But I can keep the patch around so it can eventually be re-sent to
standardize the debugobjects activation fixups. They currently need to keep a
flag around to identify statically defined objects.

Thanks,

Mathieu
