Thanks, it is really what I need.

Now I have once more question.
I made the kernel object with one check-function and all 
works fine from userland via syscall().

Is there a documented possibility to use syscalls _inside_ 
kernel code?
In other words, I need to call the function located in 
loadable kernel object from kernel, doesn't matter how 
this would be done (syscall, etc).

My goal is to avoid kernel rebuilding each time after 
function modification.

Is it possible?
