Hi Dan,
First of all, thanks for endless effort.

I didn't look at code entirely but it seems this series includes frontswap.
Finally frontswap is to replace zram?

If it is right, how about approaching one by one for easy review and merging?
I mean firstly we replace zram into frontswap and tmem and then zcache.
Regardless of my suggestion, I will look at the this series in my spare time.
