From 08aa9cce6bf3ecdfa386cf0a0be842855eac3e7d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 22 Jan 2013 18:09:41 +0900 Subject: [PATCH] perf tools: Move ltrim() to util/string.c As we have ltrim() implementation in builtin-script.c move it to the more generic location of util/string.c so that it can be used from other places.
