From ffcdedb667b6db8ee31c7efa76a3ec59d9c3b0fc Mon Sep 17 00:00:00 2001 From: "nikolay@redhat.com" Date: Sat, 6 Apr 2013 00:54:37 +0000 Subject: [PATCH] Revert "bonding: remove sysfs before removing devices" This reverts commit 4de79c737b200492195ebc54a887075327e1ec1d. This patch introduces a new bug which causes access to freed memory. In bond_uninit: list_del(&bond->bond_list); bond_list is linked in bond_net's dev_list which is freed by unregister_pernet_subsys.
