Peter Mladek reported that balloon might never refill completely after restore. This is because fill_balloon is only called once there. Calling fill_balloon repeatedly seems too aggressive, especially in light of the fact that it sleeps on failure: let's wake the config change handler and fill it asynchronously.

...reason my test VM > doesn't resume (with or without the patch). > Petr, does this work for you? Ah, I have just realized that the problem happens only after the conversion to the workqueue. It works without this patch with the current code. The balloon kthread is waken when released from __refrigerator(). I am sorry for the noise. I wanted to split the conversion to workqueues into two patches to make it better readable. We need to queue the balloon resizing work here. I wrongly assumed that the original kthread must have the same problem. Best Regards, Petr > drivers/virtio/virtio_balloon...
