I applied this patch along with Yonghong's ack to bpf tree
(though I don't have it in my mail box, but it's there in patchworks).
I'm not sure that cleanup Jakub is proposing is possible or better.
Not everything is array_size here and in other places
where cost is computed. u64 is imo much cleaner.
