From eb49a97363f020c1d7eef8bcd93865726b1fa11d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 23 Mar 2011 12:18:15 -0700 Subject: [PATCH] ipv4: fix ip_rt_update_pmtu() commit 2c8cec5c10bc (Cache learned PMTU information in inetpeer) added an extra inet_putpeer() call in ip_rt_update_pmtu(). This results in various problems, since we can free one inetpeer, while it is still in use.
