From a8305bff685252e80b7c60f4f5e7dd2e63e38218 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 29 Jul 2018 20:42:53 -0700 Subject: net: Add and use skb_mark_not_on_list(). An SKB is not on a list if skb->next is NULL. Codify this convention into a helper function and use it where we are dequeueing an SKB and need to mark it as such. Signed-off-by: David S.
