question about lists

[Julia Lawall <julia.lawall@xxxxxxxx>]

Hello,

I was wondering what is the point of code like the following:

        INIT_LIST_HEAD(&bb->list);
        list_add(&bb->list, &s->workload->shadow_bb);

As far as I can see, list_add will initialize both fields of the list_head
structure without looking at their values, so why is the INIT_LIST_HEAD
needed?

thanks,
julia
