This is a note to let you know that I have just added a patch titled ifb: fix oops when loading the ifb failed to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 7fa24219b2ab80da29e506d7e75cc6ba5a87df88 Mon Sep 17 00:00:00 2001 From: dingtianhong <dingtianhong@huawei.com> Date: Thu, 11 Jul 2013 19:04:06 +0800 Subject: [PATCH] ifb: fix oops when loading the ifb failed commit f2966cd5691058b8674a20766525bedeaea9cbcf upstream. If __rtnl_link_register() return faild when loading the ifb, it will take the wrong path and get oops, so fix it just like dummy.
