Subject: [PATCH bpf-next v3 00/27] bpf: RLIMIT_MEMLOCK cleanups
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)
- v1: https://lore.kernel.org/bpf/20220320060815.7716-2-laoar.shao@gmail.com/
