This patchset fixes two bugs in bonding module

1. The first patch adds missing dynamic lockdep class key update routine.
After bond_release(), netdev_update_lockdep_key() should be called.
But both ioctl path and attribute path don't call
netdev_update_lockdep_key().

2. The second patch changes bonding stats routine
In the current code, bonding interface collects stats of slave interfaces
when dev_get_stats() is called.
But, this has several problems.
1. Possible imbalance lock/unlocking.
2. Show incorrect stats info.
So, this patch changes bonding interface stats routine.
In addition, it fixes lockdep warning.

Taehee Yoo (2):
  bonding: add missing netdev_update_lockdep_key()
  bonding: do not collect slave's stats
