    Btrfs: new backref walking code · 4692cf58
    Jan Schmidt authored
    The old backref iteration code could only safely be used on commit roots.
    Besides this limitation, it had bugs in finding the roots for these
    references. This commit replaces large parts of it by btrfs_find_all_roots()
    which a) really finds all roots and the correct roots, b) works correctly
    under heavy file system load, c) considers delayed refs.
