Subject: [PATCH] Btrfs: make lzo the default compression scheme
Date: Thu, 26 May 2011 11:39:03 +0800 [thread overview]
Message-ID: <4DDDCB57.6090405@cn.fujitsu.com> (raw)
As the lzo compression feature has been established for quite
a while, we are now ready to replace zlib with lzo as the default
compression scheme.
