The dict keys are obtained from the static array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size. Unfortunately the way that array is declared results in any unassigned stats getting a NULL name, which will then cause visit_type_uint64 to trigger an assert in qobject_output_add_obj. The balloon_stat_names array was fortunately fully populated with names until recently: commit 0d2eeef77a33315187df8519491a900bde4a3d83 Author: Bibo Mao Date: Mon Oct 28 10:38:09 2024 +0800 linux-headers: Update to Linux v6.12-rc5 pulled a change to include/standard-headers/linux/virtio_balloon.h which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new names to balloon_stat_names. This commit fills in the missing names, and uses a static assert to guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause a build failure until balloon_stat_names is updated. This problem was detected by the Cockpit Project's automated integration tests on QEMU 9.2.0-rc1.
