Subject: [PATCHv3 0/2] zsmalloc/zram: drop zram's max_zpage_size

Hello,

	ZRAM's max_zpage_size is a bad thing. It forces zsmalloc to
store normal objects as huge ones, which results in bigger zsmalloc
memory usage. Drop it and use actual zsmalloc huge-class value when
decide if the object is huge or not.

v3:
- add pool param to zs_huge_class_size() [Minchan]

Sergey Senozhatsky (2):
  zsmalloc: introduce zs_huge_class_size() function
  zram: drop max_zpage_size and use zs_huge_class_size()
