There was a long discussion about this change within radeon and the result was that it cannot be done. [1] I don't remember the full details, but semantics of the vmap/vunmap for dma-bufs were not compatible IIRC. And the resolution was a redesign of the API.
If that has changed, I'd be happy to see this patch merged. Otherwise, it should better not be taken.
Best regards Thomas [1] https://patchwork.freedesktop.org/patch/400054/?series=83765&rev=1
