Expanding the massive Cc: with linux-doc list... Here goes. It's a quick hack from months ago, but still seems to somewhat work. At least for the kernel-doc parts. The reStructuredText lint part isn't all that great, and doesn't have mapping to line numbers like the Sphinx kernel-doc extension does. Anyway I'm happy how this integrates with kernel build CHECK and C=1/C=2. I guess Julia's goal is to automate the *fixing* of some of the error classes from kernel-doc. Not sure how well this could be made to integrate with any of that.
