Hi,
Actually problem is I have 2000 source file for
single kernel module with 2.4 kbuild architecture.
All this source file are in different directory
sturcture.
I can not split this in to multiple modules.
And In 2.4 makefile it is not tightly binded with
kbuild.
It is like complining some file and linking it,
putting it in some directory and so on and finally
making module from all linked files.
It has near about 100 makefiles for 2.4 architecture.
Now I m not able to findout the way how I will achive
this with 2.6 kbuild system because in all directory
there is one makefile, which is making intermidiate
object file, say form 10 source file, then again at
last we are linking all this intermidate object file
and making a single module.
