Author: Bas Nieuwenhuizen <[email protected]> Date: Wed Mar 8 23:45:45 2017 +0100 radv: Don't invalidate CB/DB for images that aren't modified outside CB/DB. Without stores, the only writes are fast clears, transfers and metadata initialization, each of which have the appropiate invalidations already.
