Subject: [PATCH bpf-next v3 02/27] bpf: selftests: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK in xdpxceiver
Date: Tue,  5 Apr 2022 13:08:33 +0000	[thread overview]
Message-ID: <20220405130858.12165-3-laoar.shao@gmail.com> (raw)
In-Reply-To: <20220405130858.12165-1-laoar.shao@gmail.com>

Explicitly set libbpf 1.0 API mode, then we can avoid using the deprecated
RLIMIT_MEMLOCK.
