From aab34ac8582303ef57b792710fc5dd5991477475 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 19 May 2008 20:07:58 +0200 Subject: kbuild: filter away debug symbols from kernel symbols Andi Kleen reported that he saw a lot of symbols like this: 0000000000000b24 N DW.aio.h.903a6d92.2 0000000000000bce N DW.task_io_accounting.h.8d8de327.0 0000000000000bec N DW.hrtimer.h.c23659c6.0 in his System.map / kallsyms output. Simple solution is to skip all debugging symbols (they are marked 'N').
