From 47732d886385af769449022a02c7cf0ce45d8a5c Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 29 Jun 2015 14:22:13 -0700 Subject: [PATCH] perf/x86: Make merge_attr() global to use from perf_event_intel merge_attr() allows to merge two sysfs attribute tables. Export it to be usable by other files too. Next patch is going to use that to extend the sysfs format attributes for a CPU.
