Re: RFC: COW for hugepages

[Zoltan Menyhart]

David,

Why not just add a flag for a VMA telling if you want / do not want to
copy it on "fork()" ? E.g.:

dup_mmap():

	for (= current->mm->mmap ; mpnt ; mpnt = mpnt->vm_next) {

		if (mpnt->vm_flags & VM_HUGETLB_DONT_COPY)
			<do nothing>
	}

Regards,

Zoltán Menyhárt
