Our current fixes branch is based on -rc4, and I didn't see any of
these commits in linux-next, so I took the liberty to rebase them back
onto our current branch.

I.e. pulled, but rebased.


Thanks,

-Olof

Thanks no problem at my end. But to avoid future confusion, what's
the reasoning for rebasing? AFAIK, pulling this in would have just
automatically updated your branch to -rc5, no?

The only time where pulling in a branch based on a later mainline
commit would cause problems is if your branch is based on another
series of patches you want to send separately as then you'd get
all the commits between -rc4 and -rc5 when doing the pull request.

Probably nothing new in this for your, but FYI, you can use pulling
or merging branches as a way of updating your publick branches without
rebasing or adding extra merge commits while keeping the branch
pullable.

Let's assume you have arm-soc/fixes based on -rc4, and -rc5
comes out:

$ git checkout -b my-fixes-of-the-week v3.11-rc5
# apply pending patches
...
$ git checkout arm-soc/fixes
$ git merge my-fixes-of-the-week

And then you have essentially fast forwarded your arm-soc/fixes to
-rc5 and it stays pullable ;)

Regards,

Tony

Yeah, it's not that we _can't_ pull it in, it's just that we either need to
merge in -rc5 manually first, or otherwise manually verify diffstat since
it'd otherwise cover the full delta.

My request for people to not always eagerly pick up latest -rc as base for
their branches is new for this release cycle, mostly to see how well it works
out. It would keep the history of our arm-soc changes somewhat cleaner than if
we have new -rcs "anchor in" on the graph in multiple locations like we
sometimes do now. But it might just be annoying for everyone to deal with
complying too, so we'll see how it goes.

Hmm sounds like something's not right then, at least for the fixes
branch. If you do the pull request for Linus against -rc5, it should
only show the patches you merged, not the delta from -rc4 to -rc5.

If you mean that you need to be able to diff between the earlier pull
request against -rc4 and the new pull request against -rc5, then that
should work too without showing the full delta of non-arm-soc patches.

For your branches, it should not be necessary to manually merge
any upstream tags, you can just let the branches automatically
get updated when merging in branches and pulling in branches.

Especially for the fixes branch as that should not have dependencies
to other external branches :)

Yes.. I think that's against natural way of developing things as that
requires testing against multiple trees and rebasing patches that
can often introduce new issues.

The issue of generating pull requests when there are dependencies
to earlier branches not yet merged still remains though.
