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.

NAME
ibtl - Solaris InfiniBand Transport Layer DESCRIPTION
InfiniBand (IB) is an I/O technology based on switched fabrics. The Solaris InfiniBand Transport Layer (IBTL) is a Solaris kernel misc mod- ule and adheres to the IB Architecture Version 1.1 specification and provides a transport layer abstraction to IB client drivers. IBTL implements the programming interfaces for the Solaris InfiniBand Transport Framework (IBTF), consisting of the IB Channel Interface (CI) and the IB Transport Interface (TI). The CI consists of Host Channel Adapters (HCAs) and HCA drivers. A host is attached to the IB fabric through the CI layer. The Solaris InfiniBand CI is Sun's API rendering of the InfiniBand Architecture (IBTA) "verbs" specification. The Solaris InfiniBand TI is the kernel service driver interface into the Solaris InfiniBand Transport Framework. It provides transport and communications setup programming interfaces for Unreliable Datagram (UD) and Reliable Connected (RC) transport types only. FILES
