Subject: [PATCH v7 perf,bpf 01/15] perf, bpf: consider events with attr.bpf_event as side-band events
Date: Thu, 7 Mar 2019 09:57:56 -0800 [thread overview]
Message-ID: <20190307175810.249857-2-songliubraving@fb.com> (raw)
In-Reply-To: <20190307175810.249857-1-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")
