Applied to kbuild/linux.git (kbuild-next-unstable), thanks!
[1/1] kbuild: Use --force-group-allocation when linking modules
https://git.kernel.org/kbuild/c/54747629
Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers). Patches applied to the
kbuild-next-unstable branch are accepted pending wider testing in
linux-next and any post-commit review; they will generally be moved
to the kbuild-next branch in about a week if no issues are found.
Best regards,
