From fc889aa23f4767c1c3f77fce11e17bb0a638971f Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Tue, 21 Sep 2010 18:09:00 +0200 Subject: oprofile, x86: Remove duplicate check for IBS_CAPS_OPCNT Since oprofile is setting up ibs_op/dispatched_ops in the fs only if the feature is available, its corresponding variable ibs_config.dispatched_ops is only set, if the feature is available. Thus the check is duplicate and can be removed.
