The commit db90b4969e2e ("vfio: retry creating sPAPR DMA window") introduced a build breakage on old Linux. Linux <4.2 does not define ddw in struct vfio_iommu_spapr_tce_info. Without ddw, we cannot change window size and so should give up the creation. I just exculuded the retrying code if ddw is not supported.Fixes: db90b4969e2e ("vfio: retry creating sPAPR DMA window") Signed-off-by: Takeshi Yoshimura <[email protected]> ---
