From f30c4d5a8102645f1e51156919d0c351f1d7dc74 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 26 May 2020 19:48:50 -0700 Subject: [PATCH] tcp: rename tcp_v4_err() skb parameter This essentially reverts e182eb83c960 ("Revert Backoff [v3]: Rename skb to icmp_skb in tcp_v4_err()") Now we have tcp_ld_RTO_revert() helper, we can use the usual name for sk_buff parameter, so that tcp_v4_err() and tcp_v6_err() use similar names.
