Sure, how about this?

Thanks,

Remove warning: VFS is out of sync with lock manager.

But keep it as a dprintk

The message can be generated in a quite normal situation:
 If a 'lock' request is interrupted, then the lock client needs to
  record that the server has the lock, incase it does.
 When we come the unlock, the server might say it doesn't, even
  though we think it does (or might) and this generates the message.
