IB and netdev are different subsystem, can you put it on a branch and send a
PR as the cover letter so that both subsystems can pull?

Thanks for you comment. I am  new to the process. I have a few questions regarding to this and hope you can help. First of all, the patch is mostly for IB. Is it possible for the patch to just go through the RDMA branch, since most of the changes are in RDMA? 

If the patch also needs to go through the NETDEV branch, does it mean two subsystems will pull its own part? A few follow-up questions about generating a PR, since I have never done such before.

1. Which repo should I clone and create the branch from?

2. From the example you provided, I see these people has their own branches on kernel.org, for example something like:
git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git tags/mlx5-updates-2023-06-06. 
I am not Linux maintainer. I just have repo on Github. How do I create or fork on kernel.org? Do I need an account to do so? Or I can use my own repo on Github?

3.  How to create PR in this case? Should I follow this link: https://docs.kernel.org/maintainer/pull-requests.html?

Thanks,
Wei
