Right.

Geliang, I cannot ack without any *detail* that what's the problem of
zram/zsmalloc, why we can't fix it in zsmalloc itself.
The zbud and zsmalloc is otally different design to aim different goal
determinism vs efficiency so you can choose what you want between zswap
and zram rather than mixing the features.
