Say I have to provide you > with an immutable branch, it should only contain Roger's patches, right? Well ideally it would be just minimal NAND related changes branch against v4.6-rc1. Then if Roger has a dependency to that, Roger can pull it in. Then Roger would make a branch for the GPMC changes against your minimal NAND branch. Then if there were non-trivial merge conflicts, I could pull in Roger's GPMC branch as needed. But in this case, it seems you can just merge everything via the NAND tree and problem solved. > But this also means this immutable branch has to be pulled into my > nand/next branch before all other changes touching the same set of > files, which in turn means that I'll have to rebase and push -f my > nand/next branch (which I'd like to avoid). Yeah let's not do rebases, there should be no need for it. > Or should I just pull this immutable branch in my current nand/next and > let you pull the same immutable branch in omap-soc.

But you may have other dependencies in your NAND tree so that may no longer be doable :) Usually if I merge something that may need to get merged into other branches, I just apply them into a separate branch against -rc1 to start with, then merge that branch in.
