From df20286ab1e36eaaf1f6c7e5e2c56bea1ffc26c0 Mon Sep 17 00:00:00 2001 From: Sowmini Varadhan Date: Sat, 8 Nov 2014 20:42:20 -0500 Subject: sunvnet: Add missing rcu_read_unlock() in vnet_start_xmit The out_dropped label will only do rcu_read_unlock for non-null port. So add the missing rcu_read_unlock() when bailing due to non-null port. Signed-off-by: Sowmini Varadhan Signed-off-by: David S.
