Applied to focal:linux-gcp, jammy:linux-gcp, lunar:linux-gcp, and jammy:linux-gke master-next branches.

I didn't apply to mantic:linux-gcp, as per discussion on applying to generic (https://lists.ubuntu.com/archives/kernel-team/2023-September/142776.html), this required an additional patch inclusion (1ded5e5a5931 - "net: annotate data-races around sock->ops"). No one is currently using mantic:linux-gcp, so if we get the patch on rebase from mantic generic, that should be fine.


Thanks,
