Subject: [PATCH 1/2] Btrfs: cleanup extents after we finish logging inode
Date: Tue, 28 Aug 2012 00:52:19 +0800 [thread overview]
Message-ID: <1346086340-14776-1-git-send-email-bo.li.liu@oracle.com> (raw)
This is based on Josef's "Btrfs: turbo charge fsync".
We should cleanup those extents after we've finished logging inode,
otherwise we may do redundant work on them.
