Subject: [PATCH 0/2] zsmalloc/zram: drop zram's max_zpage_size
Date: Wed, 7 Feb 2018 18:29:17 +0900 [thread overview]
Message-ID: <20180207092919.19696-1-sergey.senozhatsky@gmail.com> (raw)
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.
Sergey Senozhatsky (2):
zsmalloc: introduce zs_huge_object() function
zram: drop max_zpage_size and use zs_huge_object()
