What's .list.lock and how does that even compile?

Yes, it is a typo. This macro is not used. That is why there is no compilation error. I will remove it from the patch.

+extern bool dlock_list_next(struct dlock_list_head *dlist,
+ struct dlock_list_iter *iter);
Ugh... Why not dlist_for_each_entry(), seeing that all users end up with
the same boilerplate?

Right, I could make a dlock_list_for_each_entry() that encapsulate the boilerplate. I will work on that.

Thanks,
