Subject: [PATCH 8/9] staging: slicoss: use free_netdev(netdev) instead of kfree()
Date: Tue, 28 Sep 2010 21:08:08 +0400 [thread overview]
Message-ID: <1285693688-4763-1-git-send-email-segooon@gmail.com> (raw)
Freeing netdev without free_netdev() leads to net, tx leaks.
I might lead to dereferencing freed pointer.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
@@
struct net_device* dev;
@@
-kfree(dev)
+free_netdev(dev)
