Date: Wed, 1 Nov 2006 18:15:10 -0500 From: Dave Jones <davej@...hat.com> To: Linus Torvalds <torvalds@...l.org>, Andrew Morton <akpm@...l.org> Cc: Linux Kernel <linux-kernel@...r.kernel.org> Subject: More list debugging context. Print the other (hopefully) known good pointer when list_head debugging too, which may yield additional clues. Also fix for 80-columns to win akpm brownie points.
