 Yes, you're right. Looks like this would be more complicated but better way to 
do the thing. I'll look at migration state notifier mechanism.

 Yes, this is good idea, too much changes otherwise. But here at Samsung we 
have a project, and it has deadlines, so please understand that i try to do 
things quickly.
 Of course, you see that as soon as i make something, i post it at least as 
RFCs, because i don't want to have something misdesigned, which will be dropped 
afterwards. Cooperation with OSS is one of goals of our project.

 Thank you very much for your cooperation and explanations.
