Hello, zram writeback is currently under (heavy) rework, the series hasn't been published yet, but it's in the making for some time already. The biggest change is that zram will support compressed writeback, that is writeback of compressed objects, as opposed to current design when zram de-compresses pages before writeback. Minchan will have more details, but I guess we'll need to wait for that series to land.
