19 external module should supply a makefile that hides most of the

124 make -C $KDIR M=$PWD bar.lst
125 make -C $KDIR M=$PWD baz.o
126 make -C $KDIR M=$PWD foo.ko

417 NOTE: The method with a top-level kbuild file is recommended
420 Use a top-level kbuild file
421 If you have two modules, foo.ko and bar.ko, where
422 foo.ko needs symbols from bar.ko, you can use a
423 common top-level kbuild file so both modules are
427 ./foo/ <= contains foo.ko
430 The top-level kbuild file would then look like::
433 obj-m := foo/ bar/
437 $ make -C $KDIR M=$PWD
443 If it is impractical to add a top-level kbuild file,
