Foward declaration, that is.
You can vaguely compare it to function prototypes.

This basically says that these structs exist and are defined somewhere. You
need this
This might be the case of cyclic dependency where header files defining
these structures are also including this .h file.

Hi guys,
When I read the linux/device.h file for some device driver usage, i find some
confusions like following.
$ head -60 device.h
[...]
struct device;
struct device_private;
struct device_driver;
struct driver_private;
struct module;
struct class;
struct subsys_private;
struct bus_type;
