Davidlohr Bueso 60758d6668 perf bench futex: Sanitize numeric parameters ... This gets rid of oddities such as: perf bench futex hash -t -4 perf: calloc: Cannot allocate memory Runtime (and many more) are equally busted, i.e. run for bogus amounts of time. Just use the abs, instead of, for example errorring out. Committer note: After the patch: $ perf bench futex hash -t -4 # Running 'futex/hash' benchmark: Run summary [PID 10178]: 4 threads, each operating on 1024 [private] futexes for 10 secs.
