Included file path was hard-wired in the ocfs2 makefile, which might causes some confusion when compiling ocfs2 as an external module. Say if we compile ocfs2 module as following. cp -r /kernel/tree/fs/ocfs2 /other/dir/ocfs2 cd /other/dir/ocfs2 make -C /path/to/kernel_source M=`pwd` modules Acutally, the compiler wil try to find included file in /kernel/tree/fs/ocfs2, rather than the directory /other/dir/ocfs2. To fix this little bug, we introduce the var $(src) provided by kbuild. $(src) means the absolute path of the running kbuild file.
