other info that might help us debug this:

Chain exists of:
  &ocfs2_file_ip_alloc_sem_key --> &journal->j_trans_barrier --> jbd2_handle

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(jbd2_handle);
                               lock(&journal->j_trans_barrier);
                               lock(jbd2_handle);
  lock(&ocfs2_file_ip_alloc_sem_key);
