Subject: [PATCH -tip 0/2] perf bench futex updates
Date: Mon, 24 Oct 2016 13:56:51 -0700	[thread overview]
Message-ID: <1477342613-9938-1-git-send-email-dave@stgolabs.net> (raw)

Hi Arnaldo, here's the requested patch that gets rid of the struct alignment
tackling the main source of cacheline bouncing. In addition a small fix to
bogus inputs.

Thanks!

  perf/bench-futex: Avoid worker cacheline bouncing
  perf/bench-futex: Sanitize numeric parameters
