Are you sure because in kernel top-level Makefile contains SUBDIRS
symbol for external modules and if it contains a path then target all
becomes _all else _all becomes modules. Personally, I am not sure of
this behavior but I think if we can do obj-y instead of obj-m than
maybe this module is built-in. Sorry you already said it's not
possible but I am still curious why it doesn't in the light of
SUBDIRS.
By the way can you suggest how do I workout getting the code inside
the kernel source.
Analyzing the following from module's Makefile:
all: $(src)/crypto/gmp.h $(src)/crypto/libgmp.a
@$(MAKE) -C $(KERNEL_BUILD) M=$(CURDIR) modules
I thought maybe if i replace "modules" with "all", it might have the
same effect as what I suggested in case of SUBDIRS for kernel
Makefile.
