Hi All,

We are developing a block device driver on linux-2.6.x kernel. We want
to
distribute our driver as sum of source code and librabry/object code.

We have divided the source code into two parts. The os interface module
and the device interface module. The os interface module (osint.c) has
all the os interface functions (init, exit, open, close, ioctl, request
queue handling etc). The device interface module (devint.c) on the other
hand has all the device interface functions (initialize device, read,
write etc), these don't use system calls or kernel APIs.

The device interface module is proprietary source and we don't intend to
distribute it with source code on GPL license.

What we intend to do is, distribute the os interface module (osint.c)
with
source code and the device interface module as object code or library.
The
user will compile the os interface module on the target box and link it
with the device interface module to generate the .ko (loadable module).

We are not very sure of how to achieve this. 
Please help us address this issue.

Thanks in advance,
-Jinu
