Can we use a variable to automatically call the right version in CAR?
I know the code below will not work, but to give you an idea...
int do_printk(int msg_level, const char *fmt, ...)
{
if (ram_enabled)
return do_ram_printk()
else
return do_car_printk()
}
Or we do that with function pointer manipulation.
Comments?
