Hi Greg, Sourav removed the new field from sys/device../nodeN/meminfo as you requested; however, in nodeN/vmstat fields still get appended, as there is code that displays every item in zone_stat_item, node_stat_item without option to opt-out. I mentioned it to you at LPC. In my IOMMU [1] series, there are also fields that are added to node_stat_item that as result are appended to nodeN/vmstat.
