[ltt-dev] ltt trace files are empty

[Srikanth Krishnakar]

Dhirendar,

You just connected the markers, where are the further steps ?

I mean :

1. ltt-armall
2. lttctl -C -w /tmp/trace1 trace1

<Run your tests here, If you have any >

3. lttctl -D trace1
4. ltt-disarmall
5. lttv -m textDump -t /tmp/trace1
