It matches the tests whose name contains "user" and runs those; the mmap interface cases that file provides are 175.x, so the v1 changelog was wrong about what the command runs as well. So v2 does what you suggested instead of pointing somewhere else: the sentence that sends the reader to another file, and its link target, are both gone. The How-to section above already names test-evsel.c as the example, so the instruction for running an example moves there, next to the reference it belongs to: make -C tools/lib/perf make-tests tools/lib/perf/tests-static I built that pair from a clean tree before writing it down, and the Makefile target produces both tests-static and tests-shared. The section on heterogeneous systems keeps its text about the PMU type number; it just no longer ends with an example pointer that was to a file which does not exist.
