[PATCH v4 0/2] virtio_balloon: Fix restore and convert to workqueue
It has been long since I have sent v3 of the balloon conversion from
a kthread to a workqueue. I have gained some more experience with
the APIs in the meantime. I hope that you would like the outcome.
I have added one more patch that fixes a separate problem with
restoring the balloon after the system freeze. I have found this
when testing the conversion.
