Actually linux-aio can support to submit read/write to multi files, and
virtio-scsi does have the use case, so in future io queue should be
per aio-context as I posted 1st time. And I am wondering if multiwrite-like
APIs can fit in this situation.
Though where would you get the requests for two different files from,
within the same bdrv_plug/unplug block?
I think it is doable if io queue is per aio_context.
Yes, but that would basically mean moving linux-aio functionality to
AioContext. Effectively it's a rewrite of linux-aio.c.
