OK.
Meanwhile, there's another possible issue that I think I see:

if an entry is inserted in mcast_list after ipoib_mcast_restart_task
calls ipoib_mcast_stop_thread but before spin_lock_irqsave(&priv->lock, flags);,
then ipoib_mcast_restart_task can remove this mcast entry from the list,
without waiting for the query to complete.
