From a453be9725a1aa3f602f5b4c66eefd1fb4ba7c44 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Tue, 4 Jul 2023 19:30:49 +0800 Subject: [PATCH] cgroup/cpuset: simplify the percpu kthreads check in update_tasks_cpumask() kthread_is_per_cpu() can be called directly without checking whether PF_KTHREAD is set in task->flags. So remove PF_KTHREAD check to make code more concise.
