I first thought that this must be conditional on 
CONFIG_VIRTIO_BLK_DATA_PLANE.  However, CONFIG_VIRTIO_BLK_DATA_PLANE is 
itself obsolete:

##########################################
# adjust virtio-blk-data-plane based on linux-aio

if test "$virtio_blk_data_plane" = "yes" -a \
        "$linux_aio" != "yes" ; then
  error_exit "virtio-blk-data-plane requires Linux AIO, please try --enable-linux-aio"
elif test -z "$virtio_blk_data_plane" ; then
  virtio_blk_data_plane=$linux_aio
fi

and there's no requirement to have Linux AIO anymore.  Can you prepare a
patch to drop CONFIG_VIRTIO_BLK_DATA_PLANE, and replace patch 1 with it?

We can leave --disable-virtio-blk-data-plane and --enable-virtio-blk-data-plane
in for a couple of releases.

Paolo
