+## 独立模块的编译
+
+有些模块在开发时往往独立于内核进行组织和编译，其编译方法如下：
+
+```bash
 # 独立于内核源码编译内核外部模块，-C 指定内核源码目录（必须已经编译过），M 指定外部模块所在源码目录
 make -C <kernel source dir> M=<modules dir> modules
+# 清除外部模块的编译结果
+make -C <kernel source dir> M=<modules dir> clean
+```
+
+以上命令经常以下列形式写入到 Makefile 中：
+
+```Makefile
+all:
+    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
+
+clean:
+    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
 ```
