From 9cdfe2c709c4f6076249ced6844b2bea420739c4 Mon Sep 17 00:00:00 2001 From: David L Stevens Date: Mon, 8 Dec 2014 21:46:09 -0500 Subject: sunvnet: fix incorrect rcu_read_unlock() in vnet_start_xmit() This patch removes an extra rcu_read_unlock() on an allocation failure in vnet_skb_shape(). The needed rcu_read_unlock() is already done in the out_dropped label. Reported-by: Rashmi Narasimhan Signed-off-by: David L Stevens Signed-off-by: David S.
