Subject: [PATCH 1/9] perf, bpf: consider events with attr.bpf_event as side-band events
Date: Fri, 8 Feb 2019 17:16:57 -0800	[thread overview]
Message-ID: <20190209011705.2160185-2-songliubraving@fb.com> (raw)
In-Reply-To: <20190209011705.2160185-1-songliubraving@fb.com>

Events with bpf_event should be considered as side-band event, as they
carry information about BPF programs.

Fixes: 6ee52e2a3fe4 ("perf, bpf: Introduce PERF_RECORD_BPF_EVENT")
Signed-off-by: Song Liu <songliubraving@fb.com>
