From 231b87d10920e024efaf0f9e86e1bab7bced1620 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 18 Aug 2008 17:38:42 +0800 Subject: ocfs2: Modify ocfs2_num_free_extents for future xattr usage. ocfs2_num_free_extents() is used to find the number of free extent records in an inode btree. Hence, it takes an "ocfs2_dinode" parameter. We want to use this for extended attribute trees in the future, so genericize the interface the take a buffer head. A future patch will allow that buffer_head to contain any structure rooting an ocfs2 btree.
