You need a lot better rationale to slow down these important fast paths. Particularly the syscall path is very hot.
Is this something that is really generally useful? The context switch counters might be occasionally useful, but strace can you just give the syscall count anyways. Still not sure it really should go into the standard kernel. Perhaps just keep it as a systemtap script?
