Subject: [PATCH 01/35] perf, bpf: Consider events with attr.bpf_event as side-band events
Date: Thu, 7 Mar 2019 14:43:59 -0300 [thread overview]
Message-ID: <20190307174433.28819-2-acme@kernel.org> (raw)
In-Reply-To: <20190307174433.28819-1-acme@kernel.org>
From: Song Liu <songliubraving@fb.com>
Events with attr.bpf_event set should be considered as side-band events,
as they carry information about BPF programs.
