We use these block's in order to keep track of which blocks need to be added to the extent tree and where their roots need to be written. However we skip MKFS_SUPER_BLOCK for all of these helpers, and we don't actually need to keep track of the specific block we allocated because it is always BTRFS_SUPER_INFO_OFFSET. Remove this enum as we don't need it. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
