We now have three different kinds of extent trees in ocfs2: inode data (dinode), extended attributes (xattr_tree), and extended attribute values (xattr_value). There is a nice abstraction for them, ocfs2_extent_tree, but it is hidden in alloc.c. All the calling functions have to pick amongst a varied API and pass in type bits and often extraneous pointers. A better way is to make ocfs2_extent_tree a first-class object. Everyone converts their object to an ocfs2_extent_tree() via the ocfs2_get_*_extent_tree() calls, then uses the ocfs2_extent_tree for all tree calls to alloc.c. This simplifies a lot of callers, making for readability. It also provides an easy way to add additional extent tree types, as they only need to be defined in alloc.c with a ocfs2_get_<new>_extent_tree() function.
