[Qemu-trivial] [PATCH] linux-user/main.c: Add option to user-mode emulat

From: 陳韋任
Subject: [Qemu-trivial] [PATCH] linux-user/main.c: Add option to user-mode emulation so that user can specify log file name
Date: Tue, 8 Nov 2011 17:46:44 +0800
User-agent: Mutt/1.5.21 (2010-09-15)

  QEMU linux user-mode's default log file name is "/tmp/qemu.log". In order to
change the log file name, user need to modify the source code then recompile
QEMU. This patch allow user use "-D logfile" option to specify the log file
