I think Juan simply wants to remove the ugly hack that hooks sys_call_table. Constituting a GPL bypass is not his purpose of adding the hooks. Several similar hooks are already there.
Probably what's missing is value of adding those hooks in the kernel.org tree. I guess there is a user-level command available that runs on Linux (other than GUI-based), to analyze user/kernel performance in a detailed fashion.
Thanks, Jun
