  Here is the reproducer:

  ip netns add foo
  ip -n foo link add dummy1 type dummy
  ip -n foo link add dummy2 type dummy
  modprobe bonding
  ip -n foo link add bond1 type bond
  ip -n foo link set dev bond1 down
  ip -n foo addr add 10.10.10.1/24 dev bond1
  ip -n foo link set dev bond1 up
  ip -n foo link set dummy1 master bond1
  ip -n foo link set dummy2 master bond1
  ip -n foo link set bond1 mtu 1540

  # Move slaves to init_net
  ip -n foo link set dummy1 netns 1
  ip -n foo link set dummy2 netns 1

  # idev are still in netns foo for dummy interfaces:
  ip netns exec foo ls /proc/sys/net/ipv4/conf/
  ip netns exec foo ls /proc/net/dev_snmp6/

  ip netns del foo
  dmesg
