Patch looks pretty straightforward. Would have been nice to backport
it before the branch, but since the sysctl and /proc vectors both
reach the same data, I think this is reasonably low-risk to backport
even to the 2024Q4 branch.
With a pullup, the builds will be ok, and then it will be clear if the
pullup is trouble. But with doing this at normal pace, I think the risk
is tiny.
Just explaining why "get this in before the freeze is over" isn't always
a great plan, even if it's the outcome you want.
