在x86_64下，需要先安装这几个包：yum install lld rsync python-docutils 然后再在内核源码中先编译内核，再进入tools/testing/selftests/bpf/目录执行make，可以成功编译。 麻烦测试同学再验证一下。
aarch64下同样的，先编译内核，再进入tools/testing/selftests/bpf目录下执行make,可正常编译。
6.6上引入了 bpf_testmod，用内核模块的方式辅助bpf test，所以在编译bpf kselftest的时候会去编译 testmod.ko 这个内核模块，目前看起来这个内核模块没法在不编译源码的情况下完成编译，从而会导致 bpf kselftest 目录编译失败。为了不blcok版本测试，可以先把 tools/testing/selftests/bpf/Makefile 里的 testmod 相关内容去掉，再编译bpf kselftest 目录
