I'm one of mm developers. :)
Yes. I hope Andrew have a time to take a look.

Confused. what do you mean "this"? "zsmalloc" or "zram" or "both"?
If you mean "zsmalloc", I guess there were some lengthy thread about
"why we need a new another allocator". Unfortunately, I didn't follow it
at that time. Nitin, Pekka, Could you point out that thread? or summarize
the result.

I understand you.

It's one of problem in current mm mailing list.
As you know, many mm guys works for server, not embedded so they don't have
big interest about embedded feature so prioirty of the feature was always
low. CMA proved it and next turn is zram. Even new-comer in mm is few so
review bandwidth is always low, too. :(

How can I poke them?
The only thing I can do is just (wait, repost) * 5?
Sigh. :(
