So why not a transport feature? Is it just because the SCSI commands
for virtio-blk also require a config space field? Sorry if I missed
this upthread.

[PATCH] virtio-spec: add field for scsi command size
...ause I'm not sure that *all* devices are now safe. Are they?
I had a stress test half-written for this, pasted below.
Otherwise I'd be happy to do both: use feature 25 for
VIRTIO_F_ANY_LAYOUT and another feature bit for the virtio-blk layout
change.
Cheers,
Rusty.
virtio: CONFIG_VIRTIO_DEVICE_TORTURE
Virtio devices are not supposed to depend on the framing of the scatter-gather
lists, but various implementations did. Safeguard this in future by adding
an option to deliberately create perverse descriptors.
