Dumb question. With io_uring, how do you handle lines that straddle between chunks? I'm asking since, AFAIU, the submitted requests are not guaranteed to be completed in order.

(The easiest I can think of is submitting reads for "overlapped" chunks, I'm not sure there is an easier way and I'm not sure of how much performance overhead there is to it.)

You have to handle it manually. Remember the partial lines at the beginning/end of your chunks and merge them when their mates become available.
