From: Oleg Nesterov Date: Sun, 30 Mar 2025 13:49:55 +0000 (+0200) Subject: sched/isolation: Make CONFIG_CPU_ISOLATION depend on CONFIG_SMP X-Git-Tag: v5.4.293~11 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=97d8b168cf9439e6ab00e44a5cd9094d7dec6f7b;p=thirdparty%2Fkernel%2Fstable.git sched/isolation: Make CONFIG_CPU_ISOLATION depend on CONFIG_SMP [ Upstream commit 975776841e689dd8ba36df9fa72ac3eca3c2957a ] 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.
