Revision 1f3a090b9033f69de380c03db3ea1a1015c850cf authored by Tonghao Zhang on 12 August 2020, 09:56:39 UTC, committed by David S. Miller on 13 August 2020, 22:53:30 UTC
To avoid some issues, for example RCU usage warning and double free, we should flush the flows under ovs_lock. This patch refactors table_instance_destroy and introduces table_instance_flow_flush which can be invoked by __dp_destroy or ovs_flow_tbl_flush.
