other info that might help us debug this:

Chain exists of:
  &pipe->mutex/1 --> (completion)&req.done --> sb_writers

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(sb_writers);
                               lock((completion)&req.done);
                               lock(sb_writers);
  lock(&pipe->mutex/1);
