Does anyone know if the place I put pte_unmap is logical and safe
after several pte increments?

	pte = pte_offset_map(pmd, address);
	address &= ~PMD_MASK;
	end = address + size;
	if (end > PMD_SIZE)
		end = PMD_SIZE;
	do {
		pte_t page = *pte;

		address += PAGE_SIZE;
		pte++;
		if (pte_none(page) || (!pte_present(page)))
			continue;
		*rss += PAGE_SIZE;
	} while (address < end);
	pte_unmap(pte);

BR,

Mauricio Lin.
