-Subject: [PATCH] netfilter: nft_flow_offload: wait for garbage collector
- to run after cleanup
-
-If netdevice goes down, then flowtable entries are scheduled to be
-removed. Wait for garbage collector to have a chance to run so it can
-delete them from the hashtable.
-
-The flush call might sleep, so hold the nfnl mutex from
-nft_flow_table_iterate() instead of rcu read side lock. The use of the
-nfnl mutex is also implicitly fixing races between updates via nfnetlink
-and netdevice event.
