other info that might help us debug this:

Chain exists of:

other info that might help us debug this:

Chain exists of:
  &sb->s_type->i_mutex_key#25 --> func_lock --> tpg_instances_lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(tpg_instances_lock);
                               lock(func_lock);
                               lock(tpg_instances_lock);
  lock(&sb->s_type->i_mutex_key#25);
