From: Arnaldo Carvalho de Melo <acme@redhat.com>
If we call just:
perf bench numa mem
it will present the same output as:
perf bench numa mem -h
i.e. ask for instructions about what to run.
While that is kinda ok, using 'run all tests' as the default, i.e. making 'no parms' be equivalent to:
perf bench numa mem -a
Will allow:
perf bench numa all
to actually do what is asked: i.e. run all the 'bench' tests, instead of responding to that by asking what to do.
That, in turn, allows:
perf bench all
to actually complete, for the same reasons.
And after that, the tests that come after that, and that at some point hit a NULL deref, will run, allowing me to reproduce a recently reported problem.
That when you have the needed numa libraries, which wasn't the case for the reporter, making me a bit confused after trying to reproduce his report.
So make no parms mean -a.
