From 364794845cbc49e638b83d7ef739524291e1e961 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 24 Nov 2009 12:05:16 -0200 Subject: perf tools: Introduce zalloc() for the common calloc(1, N) case MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This way we type less characters and it looks more like the kzalloc kernel counterpart.
