Subject: [PATCH] [NET] print skb pointer in truesize bug
Date: Thu, 01 May 2008 13:00:56 +0200 [thread overview]
Message-ID: <1209639656.7067.2.camel@johannes.berg> (raw)
While debugging the mac80211 truesize problem I always wished
that I knew exactly which skb showed the problem, this makes
skb_truesize_bug() print out the pointer.
