Message-id: <4B33BE74.3030704@majjas.com> Date: Thu, 24 Dec 2009 14:18:12 -0500 From: Michael Breuer <mbreuer@...jas.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: "Berck E. Nash" <flyboy@...il.com>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, netdev@...r.kernel.org, Stephen Hemminger <shemminger@...ux-foundation.org> Subject: Re: sky2 panic in 2.6.32.1 under load (new oops) I'll be the first to admit I don't know much about network drivers... but I am wondering why __free_page(frag->page); is called in skb_put_frags when the fragment length is zero. I don't see why that page pointer wouldn't potentially be reused afterwords.
