The patches are on top of bpf-next:

 git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master

Will do.

The example schedulers need the following options enabled.

  CONFIG_BPF=y
  CONFIG_SCHED_CLASS_EXT=y
  CONFIG_BPF_SYSCALL=y
  CONFIG_BPF_JIT=y
  CONFIG_DEBUG_INFO_BTF=y
  CONFIG_BPF_JIT_ALWAYS_ON=y
  CONFIG_BPF_JIT_DEFAULT_ON=y

Thanks.
