From 2166abebc55843409327ddf6cc424cafadd33a30 Mon Sep 17 00:00:00 2001 From: Vasiliy Kulikov Date: Tue, 28 Sep 2010 21:08:04 +0400 Subject: [PATCH] staging: otus: use free_netdev(netdev) instead of kfree() Freeing netdev without free_netdev() leads to net, tx leaks. I might lead to dereferencing freed pointer.
