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.

Got it. Thanks for the explanation. The compressed writeback also makes
sense as it will save space in the backing device.

This series might not be applicable with the new direction, but anyway I will
keep an eye on the new series from Minchan.
