    Description

      It might be possible that one aio request could not be finished
      with one IO loop because of io request across stripes.

      Since -EIOCBQUEUED is returned for AIO, io loop will be stopped thus short io happen.
      There should be codes to handle these kind of cases, otherwise, fio or some other
      applications could fail.
