Jeff Mahoney c2951f32d3 btrfs: remove old tree_root dirent processing in btrfs_real_readdir() ... Commit 3de4586c52 (Btrfs: Allow subvolumes and snapshots anywhere in the directory tree) introduced the current system of placing snapshots in the directory tree. It also introduced the behavior of creating the snapshot and then creating the directory entries for it. We've kept this code around for compatibility reasons, but it turns out that no file systems with the old tree_root based snapshots can be mounted on newer (>= 2009) kernels anyway. About a month after the above commit, commit 2a7108ad89 (Btrfs: rev the disk format for the inode compat and csum selection changes) landed, changing the superblock magic number. As a result, we know that we'll never encounter tree_root-based dirents or have to deal with skipping our own snapshot dirents. Since that also means that we're now only iterating over DIR_INDEX items, which only contain one directory entry per leaf item, we don't need to loop over the leaf item contents anymore either.
