Daniel, could you remove exynos related codes from your patch set?
Your patch set would make exynos broken because you didn't consider
exporting with a gem object for exynos like [PATCH 3/3] drm/i915: explicit
store base gem object in dma_buf->priv. So I think your patch set is not
complete set, and That is why exynos needs the additional work I mentioned
above. So I just wanted to repost your patch set + new one.
However, I think not only exynos could go to common drm_gem_dmabuf directly
but also it would make your patch set to be complete set if you remove
exynos related codes from your patch set. Otherwise, we have to work twice.
one is the additional work for resolving exynos broken issue by your patch
set, and other is to replace existing dmabuf stuff of exynos to common
drm_gem_dmabuf.

Thanks,
