From 8a455b087c9629b3ae3b521b4f1ed16672f978cc Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Thu, 20 Mar 2008 16:07:27 -0700 Subject: [PATCH] netpoll: zap_completion_queue: adjust skb->users counter zap_completion_queue() retrieves skbs from completion_queue where they have zero skb->users counter. Before dev_kfree_skb_any() it should be non-zero yet, so it's increased now. Reported-and-tested-by: Andrew Morton Signed-off-by: Jarek Poplawski Signed-off-by: Andrew Morton Signed-off-by: David S.
