LSM Automatic Module Invocation

How can the LSM be used to automatically invoke custom written kernel modules?

Specifically I would like for my module to be called every time a new process is instantiated s开发者_如何学Pythono that it can do some checking on the SELinux labels -> if there is a better way (scheduler modification?) to do this let me know.

I am trying to avoid constantly polling the process list every X ms.
