Hi Josef, thanks for clarifying. By "wants to walk forward based on a particular item" you mean - find all items that have the same objectid, until objectid changes? I wrote some code once (for educational purposes) that just walked the tree irrespective of a particular objectid, so that's why I was somewhat puzzled by your change. If you decide to keep your change, can you pls update the comment of btrfs_next_leaf()/next_old_leaf().
Thanks again, Alex.
