Linux release & branch management

Hello All, I am looking for some good wiki or documentation about about Linux branches and release management. I have read in the web about the benevolent dictator model <https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows#wfdiag_...> of git is used by Linus. But what I'm looking for is the actual logistical details like what are the official blessed repos/branches that Linus' lieutenants use and where does the patch submitted by any contributor get to and how does it get to, etc. The recent email thread on submitting patches to Linus triggered this question for me. Thanks, Anand.
