Interesting, thank you for the details. This means that in some way, RHEL is ahead of Oracle Linux in terms of kernels? I don't see an UEK version tracking Linux 6.1 at all, AFAIK.
It's true that Red Hat does pull in changes from upstream for several subsystems of Linux. It's genuinely a frankenkernel mixed with code from 6.3, 6.1, etc.
But you're still beholden to what the Red Hat maintainers are pulling in and focusing on. It's still not a general follow upstream wholesale.
