I will try again tomorrow. The latter commit needs to be adjusted - not reverted. As the first commit that came from VFIO suggests, "struct phys_vec" is used instead of "struct dma_buf_phys_vec". Similarly, need to replace the usage of this struct in the latter patch (this should be the only adjustment).
