Thank you for sticking to it. Applied to bpf-next.

It took almost a year, but the final fix is imo much better
than all the previous attempts.
I suspect some tail_call users may see a small performance
degradation, but it's a trade off we had to make.
The evolution of the fix made the perf hit as small as possible.
