[ Not sure why I wasn't Cc'd on the original patch (or the one before that) but I guess I need to add tools/lib/traceevent under MAINTAINERs for perhaps tracing? ]
From: "Steven Rostedt (VMware)" <rost...@goodmis.org> The tools/lib/traceevent/Makefile had a test added to it to detect a failure of the "nm" when making the dynamic list file (whatever that is). The problem is that the test sorts the values "U W w" and some versions of sort will place "w" ahead of "W" (even though it has a higher ASCII value, and break the test. Add 'tr "w" "W"' to merge the two and not worry about the ordering.
