In the old extent tree operation, we take the hypothesis that we are using the ocfs2_extent_list in ocfs2_dinode as the tree root. As xattr will also use ocfs2_extent_list to store large values xattr enty, we refactor the tree operation so that xattr can use it directly. Although xattr is still under development, I'd like to send this patch set first for review since it is the base of storing large EA.
