Adding a key to syscall rules

Hello, I wanted to bring something up. Currently, we have the ability to add a custom "tag" or key to filesystem auditing rules. I got to thinking that this should also be done for syscall auditing. This way, admins can set a rule with a custom key and search for it later. (I have to write the search code.) Besides being useful, I think this should be done for symmetry between syscall & filesystem auditing as well. -Steve
