ldd3 9章的例子 short.c编译通不过：
开始问题是：Fix it to use EXTRA_CFLAGS.Stop.改了Makefile 的CFLAGS 为 EXTRA_CFLAGS后可以编译。
但又是config.h找不到 io.h找不到，又改为：
#include <linux/configfs.h>
#include <linux/io.h>
再编译：
出错：In function ‘short_selfprobe’:

－－－－－－－－－－
这下许多macro找不到 也grep不到，不知怎么改了。用的ubuntu /usr/src/linux-headers-2.6.31-14-generic
谁做过？怎么办？ gcc 加参数。。。。。。。。。。
不过首先的是，你确定你机子上有kernel到源代码了？
