Re: [PATCH V2 1/2] bpf: control the trace data output on current cpu when perf sampling

Show all headers | View raw

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.
