This a new version of my previous post[1].

patch#1 is the one which fix the reported bug.
  So Sergey, Borislav, would you please give it a test?

patch#2~4 is an enhancement which fix a potential race in
  lock_set_class(). But the fact is the only current user
  in kernel is lock_set_subclass(), we still have no
  user which change its 'key' in flying. So I mark it
  with RFC.

More detail in each patch :)

Thanks,
Yong
