[Qemu-devel] is x-data-plane considered "stable" ?

[Scott Sullivan]

Can anyone tell me if in any QEMU release x-data-plane is considered "stable"?

If its unclear, I am referring to the feature introduced in QEMU 1.4 for high 
performance disk I/O called virtio-blk data plane.

I've tried searching docs, but can't find any mention if its still considered 
experimental or not in the latest QEMU releases.
