There is a nice abstraction for them,\nocfs2_extent_tree, but it is hidden in alloc.c.  All the calling\nfunctions have to pick amongst a varied API and pass in type bits and\noften extraneous pointers.\n\nA better way is to make ocfs2_extent_tree a first-class object.\nEveryone converts their object to an ocfs2_extent_tree() via the\nocfs2_get_*_extent_tree() calls, then uses the ocfs2_extent_tree for all\ntree calls to alloc.c.\n\nThis simplifies a lot of callers, making for readability.
