Subject: [net-next PATCH v2 0/8] ipv4/fib_trie: Cleanups to prepare for
 introduction of key vector

This patch series is meant to mostly just clean up the fib_trie to prepare
it for the introduction of the key_vector.  As such there are a number of
minor clean-ups such as reformatting the tnode to match the format once the
key vector is introduced, some optimizations to drop the need for a leaf
parent pointer, and some changes to remove duplication of effort such as
the 2 look-ups that were essentially being done per node insertion.

v2: Added code to cleanup idx >> n->bits and explain unsigned long logic
    Added code to prevent allocation when tnode size is larger than size_t

Alexander Duyck (8):
      fib_trie: Only resize tnodes once instead of on each leaf removal in fib_table_flush
      fib_trie: Fib walk rcu should take a tnode and key instead of a trie and a leaf
      fib_trie: Fib find node should return parent
      fib_trie: Update insert and delete to make use of tp from find_node
      fib_trie: move leaf and tnode to occupy the same spot in the key vector
      fib_trie: Make fib_table rcu safe
      fib_trie: Update last spot w/ idx >> n->bits code and explanation
      fib_trie: Prevent allocating tnode if bits is too big for size_t
