Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2111953

Following helpers do not touch their struct net argument:

- bpf_sk_lookup_run_v6()
- __inet6_lookup_established()
- inet6_lookup_reuseport()
- inet6_lookup_listener()
- inet6_lookup_run_sk_lookup()
- __inet6_lookup()
- inet6_lookup()
