I can rename it to _alloc() if you prefer.

You mean turn *keys into keys[0] stub in struct flow_action? This is
embedded into struct tc_cls_flower_offload, I may need to make a
second look but I think it won't fly.
BTW, side note: I will rename keys to "array" given keys is not
semantically appropriate as you mentioned, BTW.
