From: Shrikanth Hegde Date: Fri, 8 Mar 2024 10:58:53 +0000 (+0100) Subject: sched/balancing: Remove reliance on 'enum cpu_idle_type' ordering when iterating... X-Git-Tag: v6.10-rc1~209^2~49 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=02a61f325a8e62a7c76479c5f2f7ddcba16877e8;p=thirdparty%2Flinux.git sched/balancing: Remove reliance on 'enum cpu_idle_type' ordering when iterating [CPU_MAX_IDLE_TYPES] arrays in show_schedstat() show_schedstat() output breaks and doesn't print all entries if the ordering of the definitions in 'enum cpu_idle_type' is changed, because show_schedstat() assumes that 'CPU_IDLE' is 0. Fix it before we change the definition order & values.
