I will re-considar my decision about putting my code in userspace.
I was facing some problems to do my work from kernel space.
my code need to take some decision based on some policy file,
and reading policies from a file.
This is the reason I am not comfortable in putting my code in kernel.
as reading file from kernel space is little tedious thing, and even thats not
recemended. thats y i am confused about how to tackle this problem.

This is not possible. And well, as others may advice, not at all logical. If you really need access to kernel data-structures and you feel your code needs to be called in middle of some kernel code path, a better decision might be to include your code in the kernel space itself.
Sitting in the userspace, the closest you can get to it is using call_usermodehelper() that allows you call a userspace binary.
