1pm EST is 2am KST(Korea Standard Time) so it's not good for me. :)
I know it's hard to adjust my time for yours so let you talk without
me. Instead, I will write it down my requirement. It's very simple and
trivial.

1) Please don't add any new feature like replace zsmalloc with zbud.
   It's totally untested so it needs more time for stable POV bug,
   or performance/fragementation.

2) Factor out common code between zcache and ramster. It should be just
   clean up code and should not change current behavior.

3) Add lots of comment to public functions

4) make function/varabiel names more clearly.

They are necessary for promotion and after promotion,
let's talk about new great features.
