hi,
that seems to work, but I could now load ctf trace data only in babeltrace.
I've got following error in tracecompas while trying to load the trace:

 "No trace types found to match location /tmp/ctf-data/metadata"

but I might have old version of tracecompas and Im little fuzzy
on how to upgrade to new one.. CC-ing tracecompas guys ;-)

for anyone interested, the latest perf ctf code is in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/ctf branch

thanks,
jirka
