After dropping this commit, I applied the remaining patches to the
current bpf-next and ran the selftests.
Everything passed, though the following warning was observed during
the build:
make -j 30 -C tools/testing/selftests/bpf
...
  GEN     /home/teawater/kernel/linux-ebpf/tools/testing/selftests/bpf/tools/build/libbpf/libbpf.pc
Warning: Kernel ABI header at 'tools/include/uapi/linux/bpf.h' differs from latest version at 'include/uapi/linux/bpf.h'
  CC      /home/teawater/kernel/linux-ebpf/tools/testing/selftests/bpf/tools/build/libbpf/sharedobjs/libbpf.o

Best,
Hui
