| H A D | ringbuf.c | diff 156c9b70 Mon Nov 30 15:33:36 MST 2020 Andrii Nakryiko <andrii@kernel.org> selftests/bpf: Drain ringbuf samples at the end of test Avoid occasional test failures due to the last sample being delayed to another ring_buffer__poll() call. Instead, drain samples completely with ring_buffer__consume(). This is supposed to fix a rare and non-deterministic test failure in libbpf CI.
