First, lz4hc misses one symbol export, an easy fix. Second, zstd misses pretty much all of the advanced c/d dict, c/d ctx API that we need in order to use dicts in a module. I have fixes for both in v4 on this series (I'll Cc Nick on lz4/zstd patches). I think I'll just send out v4 today, simply because there are patches there that we can re-use even if we scratch zram backends and continue using crypto API.
