The size field is added to /proc/net/fib_triestat that was the point.
Not from what I can see.
davem@sunset:~/src/GIT/net-2.6.25$ git grep -e "->size" net/ipv4/fib_trie.c
net/ipv4/fib_trie.c: t->size++;
net/ipv4/fib_trie.c: t->size--;
davem@sunset:~/src/GIT/net-2.6.25$ git grep -e "\.size" net/ipv4/fib_trie.c
davem@sunset:~/src/GIT/net-2.6.25$
Nothing uses the field, it is merely incremented and decremented.
trie_show_stats() and trie_show_usage() do not access this field.
