Nice, here is another more detailed version I made a few years back off the back of a rather excellent wait but why article :) https://labs.coruscantconsulting.co.uk/life/weeks/

Seriously, create a small report based on the logs that tracks visits, popular calls etc. It will do you good every morning to check it (charts and comparisons are great) and it will be an asset when promotion time comes around and you have define your "contribution" to the company :)

Agree on the cognitive overhead.
People will and are arguing that "it is kernel code, it should be complicated" but I really think this is backwards. Because it is low level and debugging is really cognitively intense and difficult at this level the code should be even clearer and easier to understand.

Projects should be accessible to new developers regardless of their complexity level. Even operating systems. Otherwise they will simply stagnate and die.
Also, "less skilled devs" are just people that are still learning. We've all been there.

On modern CPU architectures, the XOR technique can be slower than using a temporary variable to do swapping. One reason is that modern CPUs strive to execute instructions in parallel via instruction pipelines. In the XOR technique, the inputs to each operation depend on the results of the previous operation, so they must be executed in strictly sequential order, negating any benefits of instruction-level parallelism.[3]

I don't know why I'm even replying, this will get so much hate here, oh well...
1. Just because things aren't done "the way you would do them" doesn't mean they're "bad" or "wrong".
2. If you're not on a solo project, I've found writing correct but less "clever" code to help shorten ramp-up time for new devs and be more beneficial to future maintainability of the code-base and system.
TL;DR; Swapping values by XOR'ing may look elite and clever but hurts you in the long run.
