From 4c07a399f98278f2a784cdf71053c85a4082f4db Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 6 May 2016 10:57:33 +0200 Subject: [PATCH] s390/cache: remove superfluous locking With "s390/cpuinfo: simplify locking and skip offline cpus early" we prevent already that cpus will go away. The additional get_online_cpus() / put_online_cpus() within show_cacheinfo() is not needed anymore.
