Hello, I am studying the preempt_rt patch set, and hope to contribute once I learn more. I have a question regarding the series file, which appears to document the patches. Each section in the series file appears to have a title. Is there a decoder ring or something similar to understand what the section titles mean? For example, '# Applied upstream' is pretty obvious, and can be confirmed by looking at the mainline tree. However, I see sections such as '# Posted an applied', '#Posted', '# Post', etc. How can one understand the meaning of these titles? The best way to learn may be to write some documentation about the patch set. I will search the wiki for some hints on activities in that regard. Thanks, Joe
