Compiling kernel mnodule spanning multiple files
Hello i guys i have a kernel module which has a list.c library

I have one file mod.c (the main kernel module) and one list.c (which is the library)
Could you please help me with the following questions ..
1) Is a header file needed (list.h) to be included in the mod.c ?
2) do we need to write the list.c in the kernel mode (using #define __kernel___) and using kmalloc etc ?
3) How would you write the make file ?

Right now If i try writing list.c in the kernel mode and use the makefile that u have give it give a lot of compile errors and if i write it in the user mode it give un known symobol while loading the module somehow it is not able to link it..it would be great if you could please help.
