implemented with macros. This patch improves code readability. Reasoning behind vidd_* is a sort of "video discipline". List of macros is supposed to be complete--all methods of video_switch ought to have their respective macros from now on. Functionally, this code should be no-op. My intention is to leave current behaviour of touched code as is. No objections: rwatson Silence on: freebsd-current@ Approved by: cognet
