Subject: [PATCH] ocfs2: Improve ocfs2 Makefile
Date: Thu, 8 Nov 2018 16:55:46 +0800 [thread overview]
Message-ID: <20181108085546.15149-1-lchen@suse.com> (raw)
Included file path was fixed in 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.
