Those show zero a per my other post. However I got the impression Dave was asking about regular but larger-than-one-page allocations internal to the kernel, while the Huge* lines in /proc/meminfo refers to allocations specifically done by userland applications doing huge page allocation on a system with huge pages enabled - or am I confused?

Seems to be what vmstat -m reports.
