Right. The plan, for the record, is to augment functional tests in futextest and move all performance related tests to perf. Davidlohr's tests are independent from those in futextest. I haven't done an exhaustive comparison to see if there is overlap, but since he got to perf first, we'll determine which futextest/performance tests add value and add tose, and deep six the rest.
The functional tests may then be moved to linux/tools and futextest will then be obsolete.
