From dcb191a29ea75d9a49351fdf5abbbf37bdcea4bd Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Thu, 20 Jul 2017 15:27:39 -0300 Subject: [PATCH 131/132] tools include: Adopt strstarts() from the kernel [tonyj: non tools/perf changes live in kernel-git] Git-commit: 8e99b6d4533cf3f49dcd813155a513a5b572baef Patch-mainline: v4.14-rc1 References: fate#325865,fate#325861 Replacing prefixcmp(), same purpose, inverted result, so standardize on the kernel variant, to reduce silly differences among tools/ and the kernel sources, making it easier for people to work in both codebases. And then doing: if (strstarts(option, "no-")) Looks clearer than doing: if (!prefixcmp(option, "no-")) To figure out if option starts witn "no-".
