Subject: [PATCH v9 perf,bpf 01/15] perf-record: replace option --bpf-event with --no-bpf-event
Date: Mon, 11 Mar 2019 22:30:37 -0700 [thread overview]
Message-ID: <20190312053051.2690567-2-songliubraving@fb.com> (raw)
In-Reply-To: <20190312053051.2690567-1-songliubraving@fb.com>
Currently, monitoring of BPF programs through bpf_event is off by default
for perf-record. To turn it on, the user need to use option "--bpf-event".
As BPF gets wider adoption in different subsystems, this option becomes
inconvinient.
This patch makes bpf_event on by default, and adds option "--no-bpf-event"
to turn it off. Since option --bpf-event is not released yet, it is safe
to remove it.
