Btrfs: introduce btrfs_next_old_item
We introduce btrfs_next_old_item that uses btrfs_next_old_leaf instead of btrfs_next_leaf. btrfs_next_item is also changed to simply call btrfs_next_old_item with time_seq being 0. Signed-off-by: Alexander Block <ablock84@googlemail.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
