Hi Randy.
Simple skeleton that implemented what I described in previous
mail. I just added a "samplescheck" targets, but we should maybe
do this as part of the normal build too?
The obj- := dummy.o is needed to fool kbuild to create
a built-in.o otherwise the link will fail in Documentation/
If you need to build a module simple add a rule:
obj-m := <module>.o as usual and drop the dummy.o
Will this work for you?
