I believe that most of setups that benefit from THP has NUMA enabled compile time. But if you wanna to go this path, make an effort to cleanup other artifacts for the !NUMA optimization: the ifdef has to be gone and all callers of these helpers has to be revisited. There's more opportunities to cleanup. Like it is very odd that khugepaged_prealloc_page() frees the page. -- Kirill A. Shutemov
