From 51840f7ba393dce7624a759cc4cee8c2bedf9068 Mon Sep 17 00:00:00 2001 From: Chen Ridong Date: Fri, 19 Sep 2025 09:49:03 +0000 Subject: [PATCH] cpuset: fix missing error return in update_cpumask The commit c6366739804f ("cpuset: refactor cpus_allowed_validate_change") inadvertently removed the error return when cpus_allowed_validate_change() fails. This patch restores the proper error handling by returning retval when the validation check fails.
