If they are sleeping in a patched function, we wake them up, this will help to migrate them before they get asleep again. But it might be quite tricky. We must make sure to avoid a deadlock. We probably should not check the stack in atomic context or in time sensitive functions. An alternative would be to check the stack and try migration when the process goes into a sleep. It is a location where we should not be afraid of any deadlocks or slight delay. There should be high changes for a successful migration with a minimal impact on the system throughput.
