Oh, do not worry about this one. I can prepare a patch once we discuss and review the rest. I think you have a lot on your plate even now. There are several options how to do it. I think it would be nice not send a fake signal immediately. So we can... 1. do it after some time of waiting, or 2. we can have a knob in sysfs for an admin to send a fake signal if he does not want to wait anymore, or 3. (and this is crazy one) we can trace the progress of a migration and when there is none for several iterations we can send a signal ... Miroslav
