From fb7c03dfc48eb81bda368561f4ca162749d127c9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 20 Mar 2014 19:50:33 -0700 Subject: if_vlan: Call dev_kfree_skb_any instead of kfree_skb. Replace kfree_skb with dev_kfree_skb_any in vlan_insert_tag as vlan_insert_tag can be called from hard irq context (netpoll) and from other contexts. dev_kfree_skb_any is used as vlan_insert_tag only frees the skb if the skb can not be modified to insert a tag, in which case vlan_insert_tag drops the skb.
