Commit d7ddd0a161 ("linux-aio: limit the batch size using
`aio-max-batch` parameter") added a way to limit the batch size
of Linux AIO backend for the entire AIO context.
The same AIO context can be shared by multiple devices, so
latency-sensitive devices may want to limit the batch size even
more to avoid increasing latency.
This series add the `aio-max-batch` option to the file backend,
and use it in laio_co_submit() and laio_io_unplug() to limit the
Linux AIO batch size more than the limit set by the AIO context.
Looks like you're only going to improve the wording for the QAPI
documentation for v2, so feel free to add:

Yep, I'll add your R-b in the v2 :-)
Thanks,
