Commit 835de37603ef ("meminfo: add a per node counter for balloon
drivers") added NR_BALLOON_PAGES and exposed it in /proc/meminfo.
However, the per-node view at /sys/devices/system/node/nodeX/meminfo
was not updated, even though the counter is already tracked per-node.Add it to node_read_meminfo() so users can see balloon usage per NUMA node without having to parse the raw vmstat file.
