From 550e29bc96e6f1ced2bca82dace197b009434367 Mon Sep 17 00:00:00 2001 From: Robert Olsson Date: Tue, 4 Apr 2006 12:53:35 -0700 Subject: [FIB_TRIE]: Fix leaf freeing. Seems like leaf (end-nodes) has been freed by __tnode_free_rcu and not by __leaf_free_rcu. This fixes the problem. Only tnode_free is now used which checks for appropriate node type. free_leaf can be removed. Signed-off-by: Robert Olsson Signed-off-by: David S.
