464 NOTE: The method with a top-level kbuild file is recommended
467 Use a top-level kbuild file
468 If you have two modules, foo.ko and bar.ko, where
469 foo.ko needs symbols from bar.ko, you can use a
470 common top-level kbuild file so both modules are
474 ./foo/ <= contains foo.ko
477 The top-level kbuild file would then look like::
480 obj-m := foo/ bar/
484 $ make -C $KDIR M=$PWD
