We have merged the exynos specific map interface to real user like below, https://review.tizen.org/git/?p=platform/adaptation/samsung_exynos/libtbm-exynos4412.git;a=commit;h=32c862bf69d602a13bac127f3e15bc8ea15e4315 So please, feel free to review. I'd be happy for your reivew. :) Anyway, in Exynos case, we will use Tizen platform as a real user. This means that all interfaces to be added or modified to -next will be verified on Tizen platform.
