The issue is that object is not NULL while page is NULL which is odd but may happen if the cache flush happened after loading object but before loading page. Thus checking for the page pointer is required too.
Ok then lets revert commit 6159d0f5c03e? The situation may occur elsewhere too.
The only other call to node_match() is in ___slab_alloc(), and the page pointer is already checked there. So there is no real need to check it in node_match().
