From 119e7a22bb70d84849384e5113792cd45afa4f85 Mon Sep 17 00:00:00 2001 From: Pierre Habouzit Date: Thu, 27 Aug 2009 09:59:02 +0200 Subject: [PATCH] perf tools: do not complain if root is owning perf.data This improves patch fa6963b24 so that perf.data stuff that has been dumped as root can be read (annotate/report) by a user without the use of the --force. Rationale is that root has plenty of ways to screw us (usually) that do not require twisted schemes involving specially crafting a perf.data.
