From d152d1be5962ace0706066db71b4f05dff8764eb Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 23 Oct 2014 00:15:45 +0900 Subject: [PATCH] perf tools: Add PARSE_OPT_DISABLED flag In some cases, we need to reuse exising options with some of them disabled. To do that, add PARSE_OPT_DISABLED flag and set_option_flag() function.
