Hello,
I'm sorry for the late reply.
Currently, I'm working on a different project and the patch upstream regarding live migration is taken over to Mr. Junghyun Yoo.
So, Junghyun Yoo will send the patches within few weeks.
Regads,
Jaeyong

If you go ahead and resend his series, keep him as original author (by
using the From: line in the commit message) and of course add your
signed-off-by.
