SOFCI TEST
Can you @lyakh comment on this? Isn't this a valid point, for LL module, priv.resources.heap will hav a k_heap and container_of() points to random place? I guess this is fine if mod_heap_user is NULL, but is it?
@kv2019i I should, yes, here's my comment: "I'm sorry" :-) I had a fix for this but forgot to apply when pushing. Fixed now.
