Subject: [PATCH] Test: validate that the output of ctf-fs sink is identical to
 source
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Process all the "succeed" CTF traces with the CTF-FS sink, check the
return code of babeltrace and compare the number of events in the new
trace from the number of events in the source trace.
