[Patch net-next 0/2] net: reduce dynamic lockdep keys

[Cong Wang <xiyou.wangcong@gmail.com>]

syzbot has been complaining about low MAX_LOCKDEP_KEYS for a
long time, it is mostly because we register 4 dynamic keys per
network device.

This patchset reduces the number of dynamic lockdep keys from
4 to 1 per netdev, by reverting to the previous static keys,
except for addr_list_lock which still has to be dynamic.
The second patch removes a bonding-specific key by the way.

Cong Wang (2):
  net: partially revert dynamic lockdep key changes
  bonding: remove useless stats_lock_key
