This patch looks like it should be in the 3.8-stable tree, should we apply it? ------------------ From: "Veaceslav Falico <vfalico@xxxxxxxxxx>" commit 4de79c737b200492195ebc54a887075327e1ec1d upstream We have a race condition if we try to rmmod bonding and simultaneously add a bond master through sysfs. In bonding_exit() we first remove the devices (through rtnl_link_unregister() ) and only after that we remove the sysfs. If we manage to add a device through sysfs after that the devices were removed - we'll end up with that device/sysfs structure and with the module unloaded. Fix this by first removing the sysfs and only after that calling rtnl_link_unregister(). Signed-off-by: Veaceslav Falico <vfalico@xxxxxxxxxx> Signed-off-by: David S.
