From 6aca56c024e42577c28706a85979a6967b9b5e97 Mon Sep 17 00:00:00 2001 From: Thomas Richter <tmricht@linux.ibm.com> Date: Fri, 23 Jun 2023 11:26:30 +0200 Subject: [PATCH] s390/cpum_sf: remove check on CPU being online During sampling event initialization, a check is done if that particular CPU the event is to be installed on is actually online. This check is not necessary, as it is also performed in the system call entry point. Therefore remove this check. No functional change.
