Raw devices are controlled by the database engine so the OS kernel can be bypassed when using raw devices. System files reside on filesystem, filesystem is addressed by the kernel. So everytime a database request comes the kernel handles the request to fetch data from the system file. The kernel activities are done directly by the database engine in raw devices.
