From 424e9634887842ac59c1d06d3264aaeb18853c0b Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Mon, 16 Jun 2014 11:14:25 -0700 Subject: [PATCH] perf bench mem: The -o and -n options are mutually exclusive -o, --only-prefault Show only the result with page faults before mem* -n, --no-prefault Show only the result without page faults before mem* Makes no sense to call together. Applies to both memset and memcpy.
