This #ifdef should be in the raw-posix driver. Please try to keep the

I had the same idee, but as far as I see the callback to the completes
request is handled in block.c. raw-posix uses the aio interface and
not coroutines.
You can put it in the QEMU_AIO_READ case of aio_worker.
linux-aio.c is only for O_DIRECT, so you do not need it there.
BTW, perhaps you need to exclude the fadvise if O_DIRECT is in use?
