我在源sid的下载了aufs-source安装，不知如何编译成内核模块。运行make 好像不行
Makefile内容如下：

#!/usr/bin/make -f
# Makefile for building the aufs module in Debian
include $(M)/debian/conf.mk
include $(M)/Makefile.upstream



aufs目录下有如下文件：
aufs.h debug.h finfo.c inode.h module.c sysaufs.h
branch.c dentry.c f_op.c i_op_add.c module.h vdir.c
branch.h dentry.h fs i_op.c opts.c vfsub.c
cpup.c dinfo.c hin_ignore.h i_op_del.c opts.h vfsub.h
cpup.h dir.c hinode.h i_op_ren.c plink.c whout.c
dcsub.c dir.h hinotify.c Makefile sbinfo.c whout.h

debian file.c include misc.c super.h wkq.h
