From 5c34d2f03e4a7505a6acb71b6a1be8d85d1cde05 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Mon, 4 Nov 2019 20:27:54 +0100 Subject: trace2: add dots directly to strbuf in perf_fmt_prepare() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The initialization function of the Trace2 performance format target sets aside a stash of dots for indenting output. Get rid of it and use strbuf_addchars() to provide dots on demand instead. This shortens the code, gets rid of a small heap allocation and is a bit more efficient.
