[PATCH 0/3] allow zram to use zbud as underlying allocator

[Vitaly Wool]

While using ZRAM on a small RAM footprint devices, together with KSM, I ran into several occasions when moving pages from compressed swap back into the "normal" part of RAM caused significant latencies in system operation. By using zbud I lose in compression ratio but gain in determinism, lower latencies and lower fragmentation, so in the coming patches I tried to generalize what I've done to enable zbud for zram so far.
