Any other ways?
As an idea - maybe you can implement this feature as MAC module?
Looks for a mac_check_system_sysctl function.

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).
