nice, but could you please follow fs API names and change the
name to cgroupfs__mountpoint

I think we don't need to define the rest of the functions now,
if they are not used

	#define FS(name)                                \
		const char *name##__mountpoint(void);   \
		const char *name##__mount(void);        \
		bool name##__configured(void);          \

just follow the function name

thanks,
jirka
