Shutemov" , Jerome Marchand , linux-kernel@vger.kernel.org, Naoya Horiguchi pagewalk.c can handle vma in itself, so we don't have to pass vma via walk->private. And show_smap() walks pages on vma basis, so using walk_page_vma() is preferable. ChangeLog v4: - remove redundant vma Signed-off-by: Naoya Horiguchi Acked-by: Kirill A.
