Not sure how applications seamlessly can use the proposed hugetlb zone based on hugetlbfs. Depending on the programming language, it might actually need changes in libs/tools etc.
As far as databases are concerned, I think they mostly already grab vast chunks of memory to be used as hugepages (particularly for big mem systems)which is a separate list of pages. And actually are also glad that kernel never looks at them for any other purpose.
