Patch *your* kernel with the required kernel patches for the series Run $ kernel-headers/update --not-final ../kernel HEAD This creates the 'Updated kernel headers' commit you need Apply the patches in your series. Push to github and tag your PR with 'needs-kernel-patch'. Post to the mailing list with 'git send-email' When the kernel patch is accepted the you or the maintainer will do 'git rebase' and exec instead of pick the first commit with: exec kernel-headers/update ../kernel 12345566 To build the final commit and remove the 'needs-kernel-patch' tag. That gets force pushed to the PR and the PR merged. This keeps the headers in sync between the two projects. Jason
