The first loop only clears the pointers with RCU_INIT_POINTER(). It does not modify the list, so the 'safe' variant is not needed there. synchronize_srcu() is then called once, after that loop, to wait for in-flight readers. The actual removal still happens in the second loop, which keeps list_for_each_entry_safe().
