bonding: remove sysfs before removing devices
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@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
