Subject: [RFC PATCH v3 35/37] perf tools: Add a bpf_wrapper global flag
Date: Sun, 17 May 2015 10:57:00 +0000 [thread overview]
Message-ID: <1431860222-61636-36-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1431860222-61636-1-git-send-email-wangnan0@huawei.com>
The newly introduced flag is a indicator for 'perf bpf'. When commands
like 'cmd_record' is started using 'perf bpf', they should consider the
binding of bpf programs.
