Actually, no, it doesn't. That's only true if using 'head' as the list head
as in the helper.
It ends up being
ref = list_first_pref(&prefstate->pending_missing_keys);
vs
ref = list_first_entry(&prefstate->pending_missing_keys,
struct __prelim_ref, list);
and I have to say I prefer reading the former.
