** Description changed:
+ SRU Justification:
+
+ * Explain the bug(s)
+
+ Memory bloat and aging active ct conns can happen from any stress test
+ as we have a single orkqueue for handling the ct offload conns for
+ add/del/stats actions.
+
+ * brief explanation of fixes
+
+ The first patch (which is already upstream) splits the add, del, and
+ stats work into separate work queues. The second patch limits the number
+ of entries on the add work queue.
+
+ * How to test
+
+ Testing was done with just stress traffic with lots of conns different
+ 5-tuple.
+
+ * What it could break.
+
+ Can take a lot of memory for a long time and also causing active conns
+ to age out when not necessary.
+

ct offload actions like add/del/stats are done in workqueue which can be
bloat up in stress tests. can also cause active conns to age out.
one upstream commit to help with this is this
2ed37183abb7 netfilter: flowtable: separate replace, destroy and stats to
different workqueues
