You should make this TASK_WATCHER_FUNC() or even just TASK_WATCHER(). It
looks a little goofy in the code that uses it.

Looking at it now could you do something like,

static int __task_watcher_init 
audit_alloc(unsigned long val, struct task_struct *tsk)

Instead of a macro? Might be a little less invasive.
