Hi, Here's another gup_benchmark.c fix, which I ran into while adding support for the upcoming FOLL_PIN work. Anyway, the problem is clearly described in the patch commit description, and the fix seems like the best way to me, but the fix is not *completely* black and white. This fix forces MAP_ANONYMOUS for the MAP_HUGETLB case. However, another way to do it might be to mmap() against a valid hugetlb page file, instead of /dev/zero. But that seems like a lot of trouble and if I'm reading the intent correctly, MAP_ANONYMOUS is what's desired anyway.
