- Rename dce-os-device to dce-linux-device - dce-os-device.h header is specific to OS and is only intended to be internally used within OS. Similarly all it's exposed functions are OS specific only. - Therefore instead of having a common name for all OSs for this header file, make this header internal by including linux name to it's naming convention. - Similary rename dce_os_device struct to dce_linux_device and also rename corresponding functions from this header.
