From e734568b675c985db2026848fefaac01c22977a5 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 8 Jun 2012 16:16:04 +0100 Subject: [PATCH] oprofile: perf: use NR_CPUS instead or nr_cpumask_bits for static array The OProfile perf backend uses a static array to keep track of the perf events on the system. When compiling with CONFIG_CPUMASK_OFFSTACK=y && SMP, nr_cpumask_bits is not a compile-time constant and the build will fail with: oprofile_perf.c:28: error: variably modified 'perf_events' at file scope This patch uses NR_CPUs instead of nr_cpumask_bits for the array initialisation. If this causes space problems in the future, we can always move to dynamic allocation for the events array.
