From 6f24c8d30d08f270b54f4c2cb9b08dfccbe59c57 Mon Sep 17 00:00:00 2001 From: John Hubbard Date: Fri, 18 Oct 2019 20:19:50 -0700 Subject: mm/gup_benchmark: add a missing "w" to getopt string Even though gup_benchmark.c has code to handle the -w command-line option, the "w" is not part of the getopt string. It looks as if it has been missing the whole time. On my machine, this leads naturally to the following predictable result: $ sudo ./gup_benchmark -w ./gup_benchmark: invalid option -- 'w' ...which is fixed with this commit.
