Subject: [PATCH 0/4] mm: merge zram into zswap
Date: Sun, 18 Aug 2013 16:40:45 +0800 [thread overview]
Message-ID: <1376815249-6611-1-git-send-email-bob.liu@oracle.com> (raw)
Both zswap and zram are used to compress anon pages in memory so as to reduce
swap io operation. The main different is that zswap uses zbud as its allocator
while zram uses zsmalloc. The other different is zram will create a block
device, the user need to mkswp and swapon it.
Minchan has areadly try to promote zram/zsmalloc into drivers/block/, but it may
cause increase maintenance headaches. Since the purpose of zswap and zram are
the same, this patch series try to merge them together as Mel suggested.
Dropped zram from staging and extended zswap with the same feature as zram.
zswap todo:
Improve the writeback of zswap pool pages!
Bob Liu (4):
drivers: staging: drop zram and zsmalloc
mm: promote zsmalloc to mm/
mm: zswap: add supporting for zsmalloc
mm: zswap: create a pseudo device /dev/zram0
