Subject: [PATCH] netfilter: ctnetlink: Add missing annotation for
ctnetlink_parse_nat_setup()
Sparse reports a warning at ctnetlink_parse_nat_setup()
warning: context imbalance in ctnetlink_parse_nat_setup()
- unexpected unlock
The root cause is the missing annotation at ctnetlink_parse_nat_setup()
Add the missing __must_hold(RCU) annotation
