From 9f0722380f75a0873c9d70286df8354c6895f983 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 8 Jan 2020 16:59:05 -0500 Subject: [PATCH] net: tg3: use skb_list_walk_safe helper for gso segments This is a straight-forward conversion case for the new function, and while we're at it, we can remove a null write to skb->next by replacing it with skb_mark_not_on_list.
