~ 2hr uptime: no crashes, no new errors on dmesg, everything looks good.

This pops up after diffing the output of kselftest though:

< # ./reuseport_bpf: Unable to open tcp_fastopen sysctl for writing: Permission denied
---
> # ./reuseport_bpf: ebpf error. log:
> # 0: (bf) r6 = r1
> # 1: (20) r0 = *(u32 *)skb[0]
> # 2: (97) r0 %= 10
> # 3: (95) exit
> # processed 4 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0
> #
> # : Operation not permitted

I did not run kselftest as root. I assume it is nothing noteworthy?
