Closing this ticket.
I think you might be conflating the LRU heads/tailt structures with the
hash table bucket lists. There's a global LRU list all active items are
linked into, and then the hash table buckets can each have lists of items
if multiple items hash to the same value.
so that before bit is collapsing the singly-linked-list from that
particular bucket. (h_next, not next or prev)
