From: Vladimir Sementsov-Ogievskiy <[email protected]> We do add COW child to the node. In future we are going to forbid adding COW child to the node that doesn't support backing. So, fix it here now.
Don't worry about setting bs->backing itself: in further commit we'll update the block-layer to automatically set/unset this field in generic code.
