I've written a couple of thousand words of documentation for the XArray. I need to decide how to license it. There are no SPDX tags in Documentation/ to date, so I have no examples to crib from. 1. How does one add an SPDX tag to an rst file? 2. What license should I use? I'd like people to be able to produce dead tree versions of the documentation, but if they make improvements to it, I want to see them. Something in the CC BY-SA 4.0 vein? 3. Is there a problem with extracting kernel-doc from a GPLv2 licensed file and then redistributing the result under CC BY-SA? They seem to have the same broad intent, but lawyers may grumble. -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
