This series fixes issues with variable initialization in the virtio
balloon driver which manifest as the driver sending invalid memory
stats to the host.
v1->v2:
* Call update_balloon_stats instead of filling the buffer with
invalid tags.
* Add BUG_ON to update_balloon_stats to formalize the invariant that
all slots in the buffer must be initialized.
v2->v3:
* Remove BUG_ON and return the actual number of counters from
update_balloon_stats instead.
* Added Arnd's patch to omit VM stats if CONFIG_VM_EVENT_COUNTERS
is not defined.
Arnd Bergmann (1):
virtio_balloon: prevent uninitialized variable use
Ladi Prosek (2):
virtio_balloon: don't push uninitialized buffers to stats virtqueue
virtio-balloon: use actual number of stats for stats queue buffers
