At LinuxCon Japan I talked with Linus about how to handle this.

If you look in my for-next branch on my git repo that's here:

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git

You can cherry pick my commit:

https://git.kernel.org/cgit/linux/kernel/git/rostedt/linux-trace.git/commit/?h=for-next&id=4449bf927b61bdb4389393c6fea6837214d1ace7

commit 4449bf927b61bdb4389393c6fea6837214d1ace7

Since I don't have anything else built on top of it, and it is rather
independent (I just tried cherry-picking it to Linus's tree and it
comes in with no conflicts), he said it's fine if you just cherry pick
the commit into your tree and base the rest of your patches on top of
it.

Just state that you did so in the pull commit to Linus.

Now, I would use git to do this. Don't make a patch for it. Whoever you
send patches to should cherry pick my change and then apply the rest of
your patches.

Thanks,
