This is doing more than just changing the echo being used. It's changing the test being done.
Yes, I need Tom's review for this change. As far as I can test, this fixes the test failure. If this isn't acceptable, we can use "alias echo=echo" for this test case.
I still don't see how changing "keys=common_pid" to "keys=ip" has anything to do with the echo patch. If that is a problem, it should be a different patch with explanation to why "keys=common_pid" is broken.
This test case uses a trace_marker event to make a histogram with the common_pid key, and it expects the "echo" command is built-in command so that the pid is same while writing several events to trace_marker. I changed it to "ip" which is always same if trace_marker interface is used.
Thank you,
