other info that might help us debug this:

Chain exists of:
  &journal->j_barrier --> mapping.invalidate_lock --> &sbi->s_writepages_rwsem

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&sbi->s_writepages_rwsem);
                               lock(mapping.invalidate_lock);
                               lock(&sbi->s_writepages_rwsem);
  lock(&journal->j_barrier);
