After this patch, 'perf data convert' convert comm events to output CTF
stream.
Result:
# perf record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.378 MB perf.data (73 samples) ]
# perf data convert --to-ctf ./out.ctf
[ perf data convert: Converted 'perf.data' into CTF data './out.ctf' ]
[ perf data convert: Converted and wrote 0.003 MB (73 samples) ]
# babeltrace --clock-seconds ./out.ctf/
