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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
