Please backport commit 8173f7e2ce67 ("rhashtable: clear stale iter->p on table restart") as well to 6.12.y and below

Hi Greg, hi Sasha,

8173f7e2ce67 ("rhashtable: clear stale iter->p on table restart"), the fix for the recently assigned CVE-2026-64563, got backorted to 7.1.6 and 6.18.42, but would need to go down 5.10.y branches as well.

Can you please backport this commit as well for the remaining relevant stable series?

Thanks already!

Regards,
Salvatore

Queued for 5.10, 5.15, 6.1, 6.6 and 6.12, thanks.

Thanks,
Sasha
