The only thing remaining which I really don't like is this hash helper
library thing in here.

It's a terrible abstraction and very inefficient.  Iteration uses
function calls, as does removal.  Key comparisons use callbacks, via
indirection function pointers, also very inefficient.

Just use the "struct hlist_head" and "struct hlist_node" objects we
have generically already.  Inline the list iteration, as well as the
key comparisons and the node linking/unlinking.

Otherwise if you think your hash helpers are so incredibly useful,
propose for their inclusion under lib/ on linux-kernel

But frankly, I wish you a lot of luck with that. :-)
