note: > Most common kernels configurations provide MADV_HUGEPAGE-style behavior by default, and thus MADV_HUGEPAGE is normally not necessary.

so this might have been done automatically already on 5.4+

I tried here with go-randomx, and my pages were already hugepages even when I explicitly did not indicate so, as long as it was MAP_PRIVATE|MAP_ANONYMOUS

DataHoarder:
I didn't check how quick the scan happens, but found that these had been remapped to hugepages as long as the allocation was large/aligned ofc

In any case, explicit alignment to a 2 MB and madvise call should cover all possible kernel configurations

DataHoarder:
indeed. adding it covers the cases
