From 402537fd9f5499d1a50a6f20cdd9031d24ee2e47 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Thu, 27 Sep 2012 09:33:26 +0800 Subject: [PATCH] perf/x86: Fix typo in uncore_pmu_to_box The variable box should not be declared as static. This could probably cause crashes with sufficiently parallel uncore PMU use.
