My first thought is that migration of a free hugetlb page would need to be something like: 1) allocate a fresh hugetlb page from buddy 2) free the 'migrated' free huge page back to buddy I do not think we can use the existing 'isolate-migrate' flow. Isolating a page would make it unavailable for allocation and that could cause application issues. -- Mike Kravetz
