> 1) Extend bpftool to build up CFG information of eBPF programs and add an

>    parser now understands comments (#), continuation lines (\), and arguments
>    enclosed between quotes. Also, allow to read from stdin via '-' as input
>    file, all from Quentin.
> 
> 3) Improve BPF kselftests by i) unifying the rlimit handling into a helper
>    that is then used by all tests, and ii) add support for testing tail calls
>    to test_verifier plus add tests covering all corner cases. The latter is
>    especially useful for testing JITs, from Daniel.
> 
> 4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop
>    on x64, from Daniel.
> 
> 5) Fix one more occasion in BPF samples where we do not detach the BPF program
>    from the cgroup after completion, from Prashant.
