[RFC][PATCH] (#2) Prelim in-kernel file system auditing support

Alright, Once again, thank you to Serge, Chris, and David for all the insight. Here's the latest patch incorporating many of the changes you all suggested. There are still some things missing and not fully tested (for instance, the locking). TODO: * Make filesystem auditing enabled/disabled at runtime * Re-add comments with proper DocBook formatting * Remove Makefile changes * Move struct audit_file to a slab cache Am I forgetting something? (Soooo tired ;-)) I'd appreciate any and all comments / feedback. Thank you. -- - Timothy R. Chavez
