other info that might help us debug this:

Chain exists of:
  driver_lock --> &ictx->lock --> minor_rwsem#2

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(minor_rwsem#2);
                               lock(&ictx->lock);
                               lock(minor_rwsem#2);
  lock(driver_lock);
