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. -rohit - 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/
