Hi Peter & Jason,

Hi, Gal, Jason,

It seems the hugetlb part was overlooked?
We're testing if the RDMA fork MADV_DONTFORK stuff can be removed on appropriate
kernels, but our tests still fail due to lacking explicit huge pages support [1].

I didn't think it high priority only because I think most hugetlbfs users
should be using it shared, but maybe I'm wrong..  Then it got lost indeed.

But I definitely agree it should better be there.

Peter, was it left unchanged on purpose?
Are you planning to submit the hugetlb changes as well?

I'll prepare a fix soon and post it.  Thanks,
