A ref_count could let different modules to open/close the same device independently without interfere others in some degree. But there is still some data shared between the modules, like flag, open_flag and user_data. Moreover, it won't yield an error if A open a device, and B read from it before open it in B. Maybe alloc a new handle in rt_device_open will be the ultimate solution. But that is much bigger change and we may leave it to future development.
