Subject: net: fib_rules: Pass net to fib_nl2rule() instead of skb.
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a9ffd24b5528f800c5cc994832e05adc1fcf0a5e;p=users%2Fjedix%2Flinux-maple.git

net: fib_rules: Pass net to fib_nl2rule() instead of skb.

skb is not used in fib_nl2rule() other than sock_net(skb->sk),
which is already available in callers, fib_nl_newrule() and
fib_nl_delrule().

Let's pass net directly to fib_nl2rule().
