linux device drive II 的示例移植到2.6.x内核

	It is very simple.hehe.
	You just type:
		insmod scull.ko
		./scull_user

	Early,i want to modified deeply, but i think we just can learn linux-2.6.x interface, that is all.
	If you want to run the programming, you must recompile the linux 2.6.x kernel, add devfs support, mount devfs and sysfs.


The result is :

1.
[caolingzi@localhost caolingzi]$ cat /proc/version
