From ba492615f0d32d0210b02c14b24512b4372b13d6 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 18 Aug 2008 17:38:49 +0800 Subject: ocfs2: Add xattr index tree operations When necessary, an ocfs2_xattr_block will embed an ocfs2_extent_list to store large numbers of EAs. This patch adds a new type in ocfs2_extent_tree_type and adds the implementation so that we can re-use the b-tree code to handle the storage of many EAs.
