Why would userspace need the pci id of anything? Again, just use libpci, isn't it fast enough? Don't duplicate existing logic. Or use the hw database that libudev exports, which is already on your machine and exports all of the pci ids from libpci directly. > Standard class IDs are even sillier to duplicate. Again, why does userspace need this? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
