    Hmm, what started this thread was libhugetlbfs maintainer complained
    how "fuss" it was to create private hugetlb mapping and suggested an
    even bigger kernel change with pagetable_operations API. The new API
    was designed with an end goal of introduce /dev/hugetlb (as one of the
    feature, they might be thinking more). What motivated me here is to
    point out that we can achieve the same goal of having a /dev/hugetlb
    with existing hugetlbfs infrastructure and the implementation is
    relatively straightforward. What it also buys us is a bit more
    flexibility to the end user who wants to use the interface directly.
