From 8a7ddad8e756a72906851fdd5a6e149cbb056e0d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 18 May 2010 22:57:27 -0300 Subject: perf probe: Don't call die() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Functions that were calling xzalloc also returned -1 when, for other reasons, it could fail, and the calleds are coping with failures, so stop using die() and xzalloc().
