What I'd ask you to consider is what your end goal? Is it just to
collect a scalp (woo hoo! I've gotten a patch into the kernel)? Or
is it to actually make things better for yourself or other users? Or
are you trying to get make your self more employable, etc.

Micro-optimizations is often not particularly useful for anything
other than the first goal, and it really doesn't help anyone.

If you're just doing this in your spare time, then hopefully I hope
you are being choosy about what's the best way to use your spare time,
so the question of what your goals are going to be is a very important
thing for you to figure out. Regardless of whether it's worthwhile to
get this patch into the kernel, doing any *more* micro-optimizations
is probably not a good use of your time or anyone else's.

I'd strongly encourage you to move on to something more than just
micro-optimizations as quickly as possible.

Best regards,

- Ted
