    mm: workingset: fix use-after-free in shadow node shrinker
    
    Several people report seeing warnings about inconsistent radix tree
    nodes followed by crashes in the workingset code, which all looked like
    use-after-free access from the shadow node shrinker.
    
    Dave Jones managed to reproduce the issue with a debug patch applied,
    which confirmed that the radix tree shrinking indeed frees shadow nodes
    while they are still linked to the shadow LRU:
    
      WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200
      CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3
      Call Trace:

         __radix_tree_delete_node+0xd/0x10
         shadow_lru_isolate+0xe6/0x220
         __list_lru_walk_one.isra.4+0x9b/0x190
         list_lru_walk_one+0x23/0x30

         shrink_slab.part.44+0x23d/0x5d0
         shrink_node+0x22c/0x330
         kswapd+0x392/0x8f0
    
    This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
    inlined radix_tree_shrink().
    
    The problem is with 14b468791fa9 ("mm: workingset: move shadow entry
    tracking to radix tree exceptional tracking"), which passes an update
    callback into the radix tree to link and unlink shadow leaf nodes when
    tree entries change, but forgot to pass the callback when reclaiming a
    shadow node.
    
    While the reclaimed shadow node itself is unlinked by the shrinker, its
    deletion from the tree can cause the left-most leaf node in the tree to
    be shrunk.  If that happens to be a shadow node as well, we don't unlink
    it from the LRU as we should.
    
    Consider this tree, where the s are shadow entries:
    
           root->rnode
                |
           [0       n]
            |       |
         [s    ] [sssss]
    
    Now the shadow node shrinker reclaims the rightmost leaf node through
    the shadow node LRU:
    
           root->rnode
                |
           [0        ]
            |
        [s     ]
    
    Because the parent of the deleted node is the first level below the
    root and has only one child in the left-most slot, the intermediate
    level is shrunk and the node containing the single shadow is put in
    its place:
    
           root->rnode
                |
           [s        ]
    
    The shrinker again sees a single left-most slot in a first level node
    and thus decides to store the shadow in root->rnode directly and free
    the node - which is a leaf node on the shadow node LRU.
    
      root->rnode
           |
           s
    
    Without the update callback, the freed node remains on the shadow LRU,
    where it causes later shrinker runs to crash.
    
    Pass the node updater callback into __radix_tree_delete_node() in case
    the deletion causes the left-most branch in the tree to collapse too.
    
    Also add warnings when linked nodes are freed right away, rather than
    wait for the use-after-free when the list is scanned much later.
