other info that might help us debug this:

Chain exists of:
   &ovl_i_mutex_dir_key[depth] --> &p->lock --> &sig->cred_guard_mutex

  Possible unsafe locking scenario:

        CPU0                    CPU1
        ----                    ----
   lock(&sig->cred_guard_mutex);
                                lock(&p->lock);
                                lock(&sig->cred_guard_mutex);
   lock(&ovl_i_mutex_dir_key[depth]);
