Why I put zsmalloc into under mm firstly is that Andrew had a concern
about using strut page's some fields freely in zsmalloc so he wanted
to maintain it in mm/ if I remember correctly.

So I and Nitin tried to ask the opinion to akpm several times
(at least 5 and even I sent such patch a few month ago) but didn't get
any reply from him so I guess he doesn't have any concern about that
any more.

In point of view that it's an another slab-like allocator,
it might be proper under mm but it's not popular as current mm's 
allocators(/SLUB/SLOB and page allocator).

Frankly speaking, I'm okay whether we put it to mm/ or lib/.
But it seems Nitin and Konrad like lib/ and Andrew is silent.
That's why I am biased into lib/ now.

If someone yell we should keep it to mm/ by logical claim,
I can change my mind easily.
But I've never heard abut that until now.
