Hi,

Rather than repeat the same blurb again, see the v2 posting here:

https://lore.kernel.org/linux-fsdevel/20230327180449.87382-1-axboe@kernel.dk/

tldr - turn single segment iovecs into ITER_UBUF rather than ITER_IOVEC,
because they are more efficient.

Since v2:

- Add prep patch based on Al's suggestion on just making iov_iter_iovec()
  deal with ITER_UBUF.
- Drop previous two prep patches, as they are no longer needed.
