From 975776841e689dd8ba36df9fa72ac3eca3c2957a Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sun, 30 Mar 2025 15:49:55 +0200 Subject: [PATCH] sched/isolation: Make CONFIG_CPU_ISOLATION depend on CONFIG_SMP kernel/sched/isolation.c obviously makes no sense without CONFIG_SMP, but the Kconfig entry we have right now: config CPU_ISOLATION bool "CPU isolation" depends on SMP || COMPILE_TEST allows the creation of pointless .config's which cause build failures.
