Subject: [PATCH 07/12] Btrfs: add checksum check for log
Date: Thu, 30 Jun 2011 15:36:27 +0800 [thread overview]
Message-ID: <1309419392-17770-8-git-send-email-liubo2009@cn.fujitsu.com> (raw)
In-Reply-To: <1309419392-17770-1-git-send-email-liubo2009@cn.fujitsu.com>
If a inode is a BTRFS_INODE_NODATASUM one, it need not to look for csum items
any more.
