+Subject: [PATCH] fib_trie: Fall back to slen update on inflate/halve failure
+
+This change corrects an issue where if inflate or halve fails we were
+exiting the resize function without at least updating the slen for the
+node.  To correct this I have moved the update of max_size into the while
+loop so that it is only decremented on a successful call to either inflate
+or halve.
