Testing it, that patch definitely cuts down on recompiles after touch include/linux/pinctrl/devinfo.h a lot. It still ends up rebuilding a fair amount of odd drivers, but now the files it rebuilds at least make _some_ sense. It used to really rebuild just about everything (because pretty much everything includes <linux/device.h>). Now it rebuilds various snd/soc files,gpio stuff and mmc/mfc stuff. I'm sure it could be improved upon still, but I think this is already a fairly noticeable improvement. One odd header include down. Ten million to go. Linus
