Subject: [PATCH net-next 0/3] bonding: remove RTNL from three sysfs files

First patch might fix a potential deadlock.
sysfs handlers should use rtnl_trylock() instead of rtnl_lock().

Following files can be read without acquiring RTNL :

- /sys/class/net/bonding_masters
- /sys/class/net/<name>/bonding/slaves
- /sys/class/net/<name>/bonding/queue_id

Eric Dumazet (3):
  bonding: no longer use RTNL in bonding_show_bonds()
  bonding: no longer use RTNL in bonding_show_slaves()
  bonding: no longer use RTNL in bonding_show_queue_id()
