I'm assuming that pgalloc_{zone} is being incremented correctly in
/proc/vmstat if you have CONFIG_VM_EVENT_COUNTERS enabled (and that you're
using a recent kernel, you never mentioned your version).
Keep in mind the vm stat threshold which will purposefully neglect to
update ZVCs if it is not reached.
nr_free_pages in /proc/zoneinfo won't decrease if the allocated page was
from the pcp and is order 0; check the difference in `count' for the
allocating cpu's pageset on the target node in the same file.
