Subject: Re: [PATCH V2 1/2] bpf: control the trace data output on current cpu when perf sampling
Date: Wed, 14 Oct 2015 21:49:39 +0800	[thread overview]
Message-ID: <201510142113.R6QU6uqp%fengguang.wu@intel.com> (raw)
In-Reply-To: <1444826277-94060-2-git-send-email-xiakaixu@huawei.com>

Hi Kaixu,

[auto build test WARNING on net-next/master -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url:    https://github.com/0day-ci/linux/commits/Kaixu-Xia/bpf-enable-disable-events-stored-in-PERF_EVENT_ARRAY-maps-trace-data-output-when-perf-sampling/20151014-204158
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> kernel/trace/bpf_trace.c:239:29: sparse: symbol 'bpf_perf_event_sample_control_proto' was not declared. Should it be static?

Please review and possibly fold the followup patch.
