We have switched to memcg based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now.
This patchset cleanups the usage of RLIMIT_MEMLOCK in tools/bpf/, tools/testing/selftests/bpf and samples/bpf. The file tools/testing/selftests/bpf/bpf_rlimit.h is removed. The included header sys/resource.h is removed from many files as it is useless in these files.
- v3: Get rid of bpf_rlimit.h and fix some typos (Andrii)
- v2: Use libbpf_set_strict_mode instead. (Andrii)

Hey Yafang, thanks for the clean up! It looks good, but please make it a bit more manageable in terms of number of patches. There is no need to have so many tiny patches. Can you squash together all the samples/bpf changes into one patch, all the selftests/bpf changes into another, bpftool ones still can be just one patch. runqslower makes sense to keep separate. Please also use customary subject prefixes for those: "selftests/bpf: ", "bpftool: ", "samples/bpf: ". For runqslower probably "tools/runqslower: " would be ok as well.
Thanks for your suggestion. I will change it.
