From ef527f968ae05c6717c39f49c8709a7e2c19183a Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 20 Feb 2022 07:40:52 -0800 Subject: net: __pskb_pull_tail() & pskb_carve_frag_list() drop_monitor friends Whenever one of these functions pull all data from an skb in a frag_list, use consume_skb() instead of kfree_skb() to avoid polluting drop monitoring.
