ocfs2: make local header paths relative to C files
Gang He reports the failure of building fs/ocfs2/ as an external module
of the kernel installed on the system:
$ cd fs/ocfs2
$ make -C /lib/modules/`uname -r`/build M=`pwd` modules
If you want to make it work reliably, I'd recommend to remove ccflags-y
from the Makefiles, and to make header paths relative to the C files. I
think this is the correct usage of the #include "..." directive.
