    Description

      we don't need to declare new attributes during a file creation - we'll set them as part of dt_create(). also, we can save two declarations in tgt_txn_start_cb().

      with this a single-striped file needs ~6MB of disk and memory reserved while before we had to reserve ~33MB.
      if we could save on dnode accounting, then we'd save another 3MB.
