This plugin has two passes. The first one tries to find all functions that can be become __init/__exit. The second one moves string constants (local variables and function string arguments marked by the nocapture attribute) only referenced in __init/__exit functions to __initconst/__exitconst sections. Based on an idea from Mathias Krause [email protected].
The kernel patches required by the plugin are maintained in PaX (http://www.grsecurity.net/~paxguy1/) and grsecurity (http://grsecurity.net/).
