My bad, don't use `MAP_HUGETLB`, just use `MAP_HUGE_1GB`.

See a quick example I whipped up here: https://github.com/inetknght/mmap-hugetlb

I don't work there any more (it was a decade ago) and I'm pretty busy right now with a new job coming up (offered today).

Do you have kernel documentation that says that hugetlb doesn't work for files? I don't see that stated anywhere.

It's filesystem-dependent. In particular, tmpfs will work. To the best of my knowledge, no “normal” filesystems (e.g., ext4, xfs) will.

It works fine on my ext4 fs...
