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,
