The main reason I bailed out initially was that this would create small changes to several otherwise seldomly touched files. And then we would later come and remove drmP.h - so lots of small but incremental changes to the same otherwise seldomly edited files. And the job was only partially done. I will try to experiment with an approach where I clean up the include/drm/*.h files a little (like suggested above, +delete drmP.h and maybe a bit more). Then to try on a driver by driver basis to make it build with a cleaned set of include files. I hope that the cleaned up driver can still build without the cleaned header files so the changes can be submitted piecemal. Will do so with an eye on the lesser maintained drivers to try it out to avoid creating too much chrunch for others. And if it works out I expect the active drivers to follow the example. todo.rst item will wait until I run out of energy. Sam
