Patch 1 of this series implements the wrapper functions around setting the compound destructor and compound order for a folio. Besides the user added in patch 1, patch 2 and patch 9 also use these helper functions. Patches 2-10 convert the higher level hugetlb functions to folios. ============== TESTING =========================== LTP: Ran 10 back to back rounds of the LTP hugetlb test suite.
