From 3d8dcb3c76bb2930798f61675c33cce8945ab988 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 10 May 2011 17:13:42 +0200 Subject: [S390] oprofile: fix min/max interval query checks oprofile_min_interval and oprofile_max_interval are unsigned, checking for negative values doesn't work. Change hwsampler_query_min_interval and hwsampler_query_max_interval to return an unsigned long and check for a zero value instead.
