other info that might help us debug this:

Chain exists of:
  &of->mutex --> &pipe->mutex --> &p->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&p->lock);
                               lock(&pipe->mutex);
                               lock(&p->lock);
  lock(&of->mutex);
