I must be missing something, we had kernel source browsing online for years, e.g. https://elixir.bootlin.com/linux/v6.17.9/source/fs, this is another one, what extra features it provides. in fact the bootlin one provides some search functions but I did not spot that here. I was expecting some LLM explanation for the code, or dependency graphs etc in the AI era for a new kernel navigator...
