If anyone has any objections, please let me know. ------------------ From: Julian Anastasov commit 2627b7e15c5064ddd5e578e4efd948d48d531a3f upstream. commit 8f4e0a18682d91 ("IPVS netns exit causes crash in conntrack") added second ip_vs_conn_drop_conntrack call instead of just adding the needed check. As result, the first call still can cause crash on netns exit. Remove it.
