From 261507a02ccba9afda919852263b6bc1581ce1ef Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Fri, 17 Dec 2010 14:21:50 +0800 Subject: btrfs: Allow to add new compression algorithm Make the code aware of compression type, instead of always assuming zlib compression. Also make the zlib workspace function as common code for all compression types.
