Linus,

Thank you for some very good descriptions on proper git workflow. That
was very informative.

As new Trivial tree maintainer I'm trying to figure out how I should
manage that tree, and based on your description on git use I have a
few questions.

What I did for my first merge-window was simply clone your tree,
create a for-linus branch, add all the patches to that branch and ask
you to pull. That worked nicely that once, but I guess that wiping the
tree and starting from a fresh clone every merge window wouldn't be a
good idea - especially since I'd like Trivial to also get pulled into
linux-next.

This is what I think I should be doing going forward. I'd appreciate
it if you could comment on whether or not it's the right way to do
things.

Start off with a clone of your tree (master branch).

Pull your tree into 'master' daily (or at least often).

Create a for-linux-2.6.27 branch or the upcomming 2.6.27 merge window
and apply all the patches I currently have pendng in a mailbox to that
branch. Keep the branch reasonably up-to-date by doing a weekly git
fetch + merge from my 'master' branch that tracks your tree.

Once the 2.6.27 merge window opens, ask you to pull the
'for-linux-2.6.27' branch and once you have done so, leave that branch
alone forever.

Branch off a new 'for-linux-2.6.28' branch and repeat.

As for linux-next, I'd create a 'linux-next' branch that I would
update whenever I change one of the 'for-linux-2.6.xx' branches, by
doing a fetch from the branch into 'linux-next' and then a merge.

Does that sound sane or is there a better way?
