Subject: [PATCH] ipv6: Don't pass invalid dst_entry pointer to dst_release().
Date: Mon, 4 Apr 2011 15:55:10 -0400 [thread overview]
Message-ID: <1301946910-5530-1-git-send-email-ostr@amd64.org> (raw)
From: Boris Ostrovsky <boris.ostrovsky@amd.com>
Make sure dst_release() is not called with error pointer. This is
similar to commit 4910ac6c526d2868adcb5893e0c428473de862b5.
