    Huh? Checking...

    [root@ana tmp]# perf record -a -f sleep 1s
    [ perf record: Woken up 3 times to write data ]
    [ perf record: Captured and wrote 0.330 MB perf.data (~14404 samples) ]
    [root@ana tmp]# perf buildid-list | grep kallsyms
    a3301c8755357466e39d71b46e8f69aecf83c0e8 [kernel.kallsyms]
    a3301c8755357466e39d71b46e8f69aecf83c0e8 [kernel.kallsyms]
    [root@ana tmp]#

    In fact there is a bug, but the bug is either in 'perf buildid-list'
    showing it twice or it being recorded twice in 'perf record'.
