Please send a version that does direct block I/O similar to xen-blkback for now.
Seems xen-blkback converts the guest IO request to host bio and submit them directly. I was wondering whether this has a performance gain compared to AIO implementation.
If we get proper in-kernel aio support one day you can add back file backend support.
I talked with Dave and Zack on the in-kernel aio patch which James pointed out:
