thanks for your review, i just submit a V2 to fix it and

Change-log:
V2:
- folded previous similar standalone patch to [1/5], and add acked tag  from Song Liu
- add acked tag to [2/5], [3/5] from Song Liu
- [4/5]: move test_bpftool.py to TEST_PROGS_EXTENDED, files in TEST_GEN_PROGS_EXTENDED
are generated by make. Otherwise, it will break out-of-tree install:
'make O=/kselftest-build SKIP_TARGETS= V=1 -C tools/testing/selftests install INSTALL_PATH=/kselftest-install'
- [5/5]: new patch

Please take a look.


Thanks
Zhijian
