[PATCH v1 0/2] virtio-balloon: tweak config_changed
Since virtio-ccw doesn't work with accessing to the config registers
inside an interrupt context, this patch series avoids that issue by
moving the config register accesses to the related workqueue contexts.

[PATCH v2 0/2] virtio-balloon: tweak config_changed
Since virtio-ccw doesn't work with accessing to the config space
inside an interrupt context, this patch series avoids that issue by
moving the config register accesses to the related workqueue contexts.
v1->v2 ChangeLog:
- add config_read_bitmap to indicate to the workqueue callbacks about
the necessity of reading the related config fields.
