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
