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. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
