In original patch[1] it's placed to union with ->lru and ->slab, but in commit e009bb30c8df ("mm: implement split page table lock for PMD level") it's in union with ->index and ->freelist. That union seems also unused for pages with table tables and safe to re-use, but it's not what I've tested. Let's move it to original place. It fixes indentation at least. :) [1] https://lkml.org/lkml/2013/10/7/288 Signed-off-by: Kirill A.
