Also I'm not really sure moving transparent_hugepage_adjust will make much sense. I mentioned it because Andres in another thread said it was suggested but the real common code knowledge is about PageTransCompoundMap only, all sort of !mmu_gfn_lpage_is_disallowed for dirty logging at 4k shadow granularity is KVM internal. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
